Back in September I got a chance to preview MTB pedals and shoes from Time and I was curious to see how they performed on the trail. The Time Z-Control pedals ($125 MSRP) are designed for freeride/DH/BMX and are so named for their Z-shaped side profile. I soon found out these are versatile pedals that can stand up to serious abuse!
The Z-Control features an aluminum body with machined surfaces for a slight weight reduction (525 grams per pair). The Z-Control pedals also come with a chromed steel axle to prevent corrosion and are tough enough to stand up to the abuse of free riding and shuttle running. To keep things running smoothly the Z-Control sports a bushing as well as a single bearing up front. Everything is well sealed to keep the dirt out which ensures these pedals will last.
The cleats on the Control-Z pedals look very similar to those found on CrankBrothers eggbeaters and like the eggbeaters you have a choice between setting a 13 or 17 degree pedal release angle. This is accomplished by choosing how you install the cleats (see instruction sheet for further installation info). I tested the bike with both settings and even though I’ve been riding for a very long time and consider myself an expert, I still chose the tighter 13 degree release angle. For me the 17 degree option was too much and made it more difficult to remove my feet from the pedals.
The Time Control-Z cleats are 100% compatible with any cleated MTB shoe so there’s no need to invest in a new set of kicks. These pedals also boast an oversized platform that Time claims will improve power transfer but I didn’t really experience that myself. The oversized platform did make it easier to catch the pedal when clipping in which is definitely a plus in freeride / DH situations.
Riding along the trails with the Time Z-Control I have to say that these pedals are tough. Despite hitting large rocks that would shatter the casing of lesser pedals, the Z-Controls held up just fine. Since these pedals are solid aluminum they did show some signs of abuse but they continued to function like new (though I did get a few small dings and scratches).
In muddy conditions the Z-Control pedals worked about the same as they did when they were clean, though getting clipped in took a bit of getting used to. I’ve been riding another brand of pedals for a long time and I’m used to clicking in a certain way. Once I was comfortable with the motion it still seemed to take a little bit more effort to lock into the Z-Contorls than with other pedals I’ve tried.
The float on the Time Z-Control pedals is a nice touch which allowed me to swerve a bit on the bike and slightly pivot on the pedals without inadvertently releasing my feet. The ability to swivel comes in handy when navigating tricky rock gardens and allows the rider greater body motion for threading tight lines along the trail.
Overall the Time Z-Control pedals work well, won’t clog up with mud and dirt, are adjustable, and can take a beating on the trail. These pedals offer a great value for the money, especially for those who like a larger platform clip-in pedal system.

Thanks to the folks at Time for providing these pedals for review.
A few weeks back I got an invitation from W.L. Gore & Associates, makers of Gore-Tex, Gore Bike Wear, and Gore Ride-On Cables (among many, many other things), to come visit them in suburban Philadelphia and learn about their products. Although I’ve owned a few Gore products over the years, I didn’t know the whole story so I decided to take them up on their offer last week. If you’re a geek like me you’ll be fascinated to learn how Gore-Tex is made and why it works so well.
How Gore-Tex is made (skip this if you hated science class)
The Gore-Tex membrane is actually created from something called Polytetrafluoroethylene or as it’s know in the biz, PTFE. PTFE is synthesized from fluorspar (a mineral) and other chemical ingredients to form a white powder which is then polymerized to form a plasticy material. The Gore company figured out that if you expand PTFE you basically get a membrane with advantageous properties like those of Gore-Tex. This expanded PTFE is known as ePTFE and in its basic form it’s very similar to the teflon tape used for sealing pipe threads.
Gore has found a way to use ePTFE in everything from cycling apparel to coatings on derailleur cables to even artificial human arteries. At its core Gore is a technology company and they’re always finding innovative ways to use this stuff. It also helps that many of the employees are outdoor nuts like us
What Gore-Tex does
Gore-Tex basically does two things that you’ll appreciate when riding in the rain: it’s waterproof and it’s breathable. The pores inside a Gore-Tex membrane are approximately 700 times smaller than a drop of water yet 20,000 times larger than a vapor molecule which keeps water out but allows body vapor caused by sweat to be released. If you’ve ever worn a cheap plastic poncho on a bike ride you know how quickly you get sweaty and drenched from the inside which sorta defeats the purpose of rain gear in the first place.
Gore-Tex glove demo showing how a wet hand will eventually dry out, even under water
Beyond the Gore-Tex membrane itself (which is laminated inside fabric so you can’t usually see it), the key to keeping you dry on a wet ride is a coating called DWR. DWR is applied to the outside of a garment to allow water to bead up when it hits. Through normal outdoor use DWR may degrade over time but it’s simple to “re-activate” it - just wash and toss it into a warm dryer! A Gore-Tex jacket with degraded DWR may feel wet (and cold) in the rain as the outer fabric gets wetted out but Gore guarantees you’ll stay dry inside.
The Gore Quality Process
One thing I didn’t realize is that Gore doesn’t just sell liners and labels to outdoor gear companies like the North Face, Sidi, and Pearl Izumi - they actually laminate and bond the fabrics in house and perform extensive testing before they’ll put their name on any product (more on the testing process in Part II of this article). In fact Gore guarantees every product with the Gore-Tex label and will replace or repair any defective item. It’s crazy to think that if your Pearl Izumi Barrier GTX MTB shoe springs a leak Gore will replace it (not Pearl Izumi) but that’s how confident Gore is in their technology.
Next week I’ll follow up with Part II of my visit to Gore where I’ll talk about the testing facilities (including the rain room and comfort chamber) and some of the newest Gore technology. In the meantime, check out these reviews of the Gore Countdown jacket, Gore Ride On cables, and the Gore Freeride Shorts & Alp X Jersey.
I’m sure many of you already read my review of the Maxxis Ardents - if you haven’t what are you waiting for? OK, now that we’re all up to speed, I have another great set of tires from Maxxis that are perfect for those who don’t quite have the clearance for using the Ardents but need the same level of grip and control.
The Maxxis Minions come in two versions: a double-ply, 2.5″ DH monster and a more XC-friendly, single-ply 2.35” tire ($53 MSRP). The thinner, 2.35″ tires are just wide enough that they provide the rider with the extra control and traction that comes with more rubber plus the added volume to help reduce pinching and rim dings.
The Minions are sold as specifics meaning that the front tire tread pattern is different from the rear tire tread pattern. Clearly this is a good idea because front and rear tires have different functions. The front tread pattern is designed to roll efficiently and provide extra traction under braking as well as cornering. The rear tire is designed to keep itself clean and provide traction for acceleration as well as braking. Below you have the images of the tread patterns, front tire on the left and the rear on the right.
Installing these was painless and took me all of 10 minutes. This time I used new tubes also from Maxxis (FR-specific tubes that are 1.2mm thick) and a dusting of talcum powder. I inflated the tires to 40PSI (my usual beginning pressure) and I was off to the trails.
I decided to take these tires to 3 stages in Collingwood for the first test ride. I chose 3 stages for its fast rolling hills and switchbacks along with its variety of terrain types (rock gardens, hardpack singletrack, river crossings, and a few softer spots that never see the sun).
Starting off on a series of rolling hills that switch back to back and up and down gave me a good indication of how well the Minions hold a line while accelerating and decelerating. I was really impressed with how smoothly the tires rolled and how little energy was required to move these tires, thanks in part to the double row of center knobs. When I got comfortable and began to really lean hard into corners I got the same warm fuzzy feeling I got with the Maxxis Ardents. Tire squirm was virtually non-existent with zero additional roll or pitching. The Minions delivered true tracking through corners.
Smashing these into rock gardens and rougher terrain I felt comfortable enough right away to pretty much go at the pace that I usually like to travel - fast or faster :). All kidding aside, the Minions felt like they were tracking like a well-behaved bloodhound. Even when the tread got wet these did a decent job holding their own over rocks and rough roots. On especially smooth, slick rock and slimy, mossy roots the Minions didn’t grip so well, but then again, what tires do?
All in all, if you’re thinking about getting these tires I’d say go for it. Of course if you’re a pure XC racer kind of person then these may not be for you - stick to something skinnier and lighter.
My overall impressions for the pair
8 out of 10 for climbing
8 out of 10 for rolling and efficiency
8 out of 10 for loose conditions
8 out of 10 for cornering
9 out of 10 for stopping in a straight line

Thanks to the folks at Maxxis for providing these tires for review.
Introducing the 2010 Opus Nelson 1 (MSRP $4160.00 CDN), the much anticipated freeride bike that has been 2 years in the making. With a full 7-inches of travel front and back, this machine is purpose built. A floating shock incorporated in a VPP-style suspension manages the rear travel and a Totem coil fork up front with a onepointfive steering tube will keep you on the path, what ever that path may be.
With full head of steam on your hands you’re gonna need to stop this beast so Opus decided to use Avid Code brakes front and back, with a 8″ rotor up front and a 7″ rotor in back, giving you just enough stopping power to tame that wild beast. The Nelson is tricked out with SRAM components including a Truvativ Holzeller 36T crank, SRAM X9 trigger shifter, and SRAM X9 long cage rear derailleur. Seat post, stem, and bar are all FSA Gravity-Lite components. Novatec hubs keep things rolling (135mm through axle rear, 20mm front) and the hoops are Mavic’s 28mm wide EN521 32 hole rims. Geax Neuron 230 TNT tires provide the rubber to meet the trail.
Taking a closer look at the Nelson you can see this machine is built for abuse. With large, oversized, manipulated top and down tubes and a one and a half inch head tube, this front triangle can take any abuse that bike parks and downhill slopes will dish out. The folks at Opus (Quebec, Canada) really spent time figuring out what their customers wanted in a freeride bike. Most of the initial product testing was done in BC with many tweaks made as a result of those sessions. Taking a quick look at this bike you can see the time was well spent considering durability and ease of maintenance.
Case in point: the oversized rear end allows you to use a 12×135mm through axle rear wheel which will save a bit of weight compared to a 12×150mm but also noticeably stiffens up the rear triangle. The use of oversized bearings on the pivot points, along with the oversized brace between the left and right seat stays, contribute to the overall strength and stability of the rear triangle and suspension. Up front you have the 180mm travel, 40mm stanchion Totem coil fork combined with a one and a half inch steering tube which takes care of front end stability and strength.
As with any FS mountain bike, getting the Nelson dialed in requires setting the front and rear suspension for your weight and riding style. On the front end, the Totem Coil has Mission control settings and Dual Flow rates that need to be customized. Using the guide provided on the Rockshox website, I started off with their recommendation of 4-4-1, and then went from there for my personal taste of a slightly more plush ride (I hit many rock gardens and I need a softer compression for that). I ultimately found that my low speed (silver knob) setting was 6 clicks and since I’m on the heavier side (195lbs) I ended up with 14 clicks rather than the 12 that they recommended as a starting point.
Now it’s time to set the rear suspension sag. The medium-sized Nelson comes with a 400 lb spring which may sound like a lot but for those who are heavier than 200 lbs, you’ll need at least a 450 or 500 lb spring. Once the sag is set at about 25 - 30% (preloading the coil), you can work on rebound. Here you’re looking to set the shock so that the bike won’t spring up too fast. Start with a little rebound and hit a few bumps in rapid succession. If you feel like you’re getting bucked off the back of the bike, keep adding clicks until the ride smooths out. You’ll know when you go to far when the rear end starts to lose travel over each bump.
Descending
Well, once the suspension is dialed in, the slack 66 degree head tube, 68 degree seat tube, and fairly generous 50mm stem will place you in a comfortable position, ready to roll! Now with numbers like these this bike is meant to do one thing very well: point down and go. The great thing about the Nelson is just how well the bike descends and I found that the faster the bike started to go, the better it handled. Keeping up speed on the Nelson seems to be the trick to make it work its magic.
One comment that I made with a few of my crew on a photo shoot was how easy it was to take the bike over drops. I found that 3 to 6 foot drops were nothing for the Nelson. Just to give you an idea, picture yourself going over a sidewalk curb at medium speed - that’s how the Nelson felt on the 3 to 6 footers. For the brave, 10 to 12 foot drops are actually even more fun. Taking a look at the drop pic below you can see that the bike just soaks up the impact like it’s nothing, If you look carefully you can also see that the bike used all its travel on this particular jump. Hey, when you’re a freerider you learn how to use everything you’ve got - in this case I had 7 inches! Nailing jumps like the one below was simple and easy but with a bike like this you have to remember to keep your weight slightly behind the bottom bracket. Due to the oversized construction I found that off big hits the rear triangle sometimes brushed on my calf if my knees were tucked in a bit.
Pictured below is the 10ft drop sequence.
Here is a short video on the OPUS Nelson 1 at Kelso’s DH run.
Cornering / Railing
At low speeds this bike did fairly well cornering, however the slack head angle would probably cause the steering to feel a bit heavy if it weren’t for the wide 28-inch bars. At speed the bike behaved totally different and allowed me to use hip motion to change direction rather than steering input. With the wider bar and short stem the Nelson placed me in a perfectly centered position to allow for rapid changes in direction. Hitting berms and twisty sections between trees was a breeze and fun.
Upgrades
Having some time to play with the bike I managed to do some part swapping and found a few upgrades that would make this great bike even better. For starters, the wheels that come with the Nelson are decent and work well however I found that slapping on a set of Mavic Crossmax SX wheels with a set of Maxxis Ardents (2.40 instead of 2.30) made the bike stick so much better in the corners and the lighter mass of the wheels made this come out of corners a bit quicker. I also found myself wishing I had my Crankbrothers Joplin mounted on this bike so I could change the seatpost height without stopping. Up front a Hammerschmidt would give you a granny gear as well as the overdrive for pointing downhill. Plus the added clearance of a Hammerschmidt would also be a benefit when hitting big obstacles.
Overall
For my first time out on a freeride bike I would have to give a big thumbs up for the Nelson. It’s a fun ride, a solid build, and a no nonsense set-up that doesn’t ever harsh the flow. The frame is solid and the choice of front and rear suspension gave me a comfortable ride with no issues. If I had $4200 CDN to spend on a bike I would certainly give the Nelson serious consideration. If your budget isn’t quite that high, OPUS also has the Nelson 2 which is downgraded a bit with X-7 shifting, Husselfelt cranks, and a Domain fork but at just $2960.00 CDN. Sweet.

Just a quick thanks to my bud Ryan for helping with the video as well as the nice folks at Opus for sending the bike over for allowing me to hit the slopes for my test.
Over the weekend you may have noticed some changes we’re rolling out to the MTB review pages here on singletracks and I wanted to talk about some of the new features. In terms of look and feel, the gear pages are following the template of the trail pages with tabs, key stats at a glance, and an enhanced dashboard. For those following along at home, take a look at the review page for the Garmin Edge 705 GPS.
Info tab: Keeps most of the same info as before but we’ve also added gear recommendations to the page. We’ll continue to tweak the recommendations based on member ratings and offer more in-category links to help you find the best stuff. We also moved stats from the left side of the page to the front and center. Reviews follow the official product details and specs.
Pro reviews: Element22 has written dozens of detailed reviews of MTB products from wheels to brakes to bikes and this tab links you directly to applicable articles. Of course many products still don’t have Pro Reviews so on this tab you can find out how to contribute your own detailed product write-up to singletracks!
Photos: This functionality has been around all summer but now it gets its own tab. View member photos of MTB gear in action. For example: Did you know singletracks has 55 photos of the Trek 4300 mountain bike alone? Scary.
Video: Now you can view and share videos of the best mountain bike products. We’ve been really surprised at the quality and quantity of video reviews, instructions, and promos already available online so we created this tab as a place to get all. Help us fill this tab up by adding product videos you find on sites like Youtube and Vimeo!
How-to: Like the Pro Review tab, this is the place to find articles explaining how to install, repair, maintain, and operate all types of mountain bike equipment. So far we have articles on servicing Manitou forks, loading data on Garmin Edge GPS units, and installing disc brakes.
In addition to the new stuff, you can still sign up for email alerts for items, add stuff to your own/wish lists, and write product reviews. Add your content to improve this MTB review resource!
So this may be a bit on the late side but seeing that most of this stuff still hasn’t hit the stores yet I thought I’d share these pics. What I have here is a compilation of my favorite photos from the show with some brief commentary so sit back and enjoy!
By far the coolest frame set I saw (next to the Banshee Legend) is the Intense 951 pictured above. I found myself just staring at this bike for far to long and almost missed my next appointment. Up close to this frame set you can see the quality work that went in to making this one of the most desirable DH frames around. With 150mm G3 rear axle spacing, one point five head tube, and over 8 inches of travel provided by an ohhh so nice Cane Creek double barrel rear shock this bike looked delicious.
Above, the same Intense 951 in red. Still nice, and this one was built up with Shimano Saint components and an Industry 9 wheel set with a Fox 40 RC2 up front and a DHX RC4 in rear. Can you say Sweet?!
Here is something that I personally want and not just for the red and orange anodized finish. The Ellsworth Rogue is a freeride bike with attitude. Not only does it look great but I had a chance to test ride one like this at Bootleg and it was super fun (the only down side - the run was too short). With 8 inches of rear travel and the Fox 40 RC2, this bike is a kick-butt machine.
It was hard to stop looking at Intense with all their models so close yet oh so far away. Here we have a pair of Uzzi frames. The Uzzi in blue has a Fox DHX Air 5 and the Red has the standard DHX 4 coil. You can also get this bike with the Cane Creek double barrel, at a cost of course. For those who plan on taking big hits and hitting the park all day long you may not need look any further than the Uzzi.
This Ibis above boasts builds in the 25 pound range with 5.5 inches of DW link rear travel for those who want a quicker, snappier ride on a bike that won’t punish you too much after riding all day long. The Ibis can be ordered in various trim levels from Sram XX or X-9 group parts to Shimano XTR, XT or SLX.
I love cut-aways of bike stuff and there were plenty at Interbike to ogle. Here you can see a cut-away of the Fox RP23 with boost valve technology on your left, the new improved DHX AIR RC4 in the middle, and a 32mm F series front fork with Fit technology (borrowed from the 36 and 40mm forks) on the right. The Fit damper now allows the engineers to further save weight on the 32mm line-up by reducing the amount of fluid needed in that damper housing. Get close to a new 32mm fork and you will also notice that the engineers changed up the way the fork works as well by placing the rebound adjuster on the bottom (previous models placed the lock-out on the bottom). Check out FoxRacingShox.com for further information.
Walking around Interbike you couldn’t help but notice the Mavic display. Looking at the line up for next year they have really improved the wheels, especially for the trail and enduro riders out there. The new Crossmax ST wheels are even lighter than before, now at just 1615 grams. Mavic also changed up the graphics on the rims.
The new Deemax Ultimate at 1915 grams a set is absolutely crazy light for a full-on DH wheel set. These wheels come with all the bells as whistles to make them both strong enough and light enough for the demands of the DH circuit. The Deemax wheels also sport my favorite ITS4 cassette body and ISM (inter spoke milling with central spine) which reduces mass on the rim without loosing strength. Check out Mavic.com for more info on these and the rest of the line up.
Here is just a random photo of the new carbon Ellsworth Enlightenment. What caught my eye here is the fine machine work on a part that just holds the brake and rear wheel. This attention to detail is second to none.
This bike was another one of those that you had to stop and drool over for a while. The Banshee Rune pictured here was shown in flat black and bright orange components. The Crankbrothers Iodine AM wheels along with Race Face AM cranks and bars (not shown) really made this bike and the components just added to the already awesome construction of this frame. You have to check out the Banshee website for more information on this bike as well as the rest of their line-up.
Hubba hubba… umm sorry. But just in case you have no clue what this is, this is the new aluminum version of the Dorado DH fork from Manitou. I am dying to do a review on this unit. This fork has everything a racer would want: high and low speed compression, rebound, and top-out and bottom-out control. To top it all off, these forks are assembled right here in the States. With 36mm stanchions and an inverted design this fork will take a kicking and keep on bouncing.
Answer is back with all new products this year. New thin and stout pedals, super wide 780mm DH bars, and 720mm AM bars are also available. The bars will come in two versions: a one-inch and two-inch rise for the AM Bar and half-inch and one-inch rise for the DH bar. A direct mount stem for the Dorado allows you to change the reach from 45, 50, 55mm while providing a strong grip to the bar with its wide face plate.
Sun-Ringle has totally revamped the line-up with new hubs, rims and colors that promise to impress everyone. The hub shot above gives just a taste of what you can expect to see in 2010. Straight pull spokes, anodized hubs and aluminum cassette bodies.
What’s not to like about the new Hayes Stroker Ace look for this year? Now in jet black with bronze-ish piston covers, this is one great looking, high performance brake set. Along with the Stroker Ace the entire line up now boasts new graphics and now the Stroker Grams come in all white.
Well that does it for my list of favorites from Interbike - hope you enjoyed the pics!
I’ve been using Nuun Active Hydration tablets ($19.50 for a 3 pack) for a while and just wanted to give a quick heads up on this product. Unlike other tablets on the market, these babies can be used in your hydration pack without fear of growing a funky science experiment. The Nuun tablets are also crazy easy to use, no measurements required - just pop in one tablet for every 500ml of water in your hydration pack. For instance, I have a 3L pack so I pop 6 tablets in and go.
Nuun tablets add a little flavor to your water but more importantly they deliver a combination of fundamental minerals and electrolytes that promote hydration during exercise. The tablets also feature a catalyst to speed up the absorption of water while you’re active. The best part? No added carbohydrates or sugars means no harsh crash later.
Now everyone is different so I won’t offer any performance claims however I can tell you that I didn’t feel any worse off using Nuun. I actually felt pretty good on rides when I used Nuun and I enjoyed all the flavors I tried including lemon+lime, tri-berry and banananuun. I was also happy that cleaning my hydration pack was not an issue; a simple rinse with water (and occasionally some dish soap) left the pack without a sticky mess afterward.
If you’re interested in more details, check out the Nuun website.
Sorry for the late announcement but here it is: The dirtiest mountain bike drivetrains on the planet. Ok, so maybe there are nastier chains, cassettes, and cranks out there somewhere (probably in a third world country) but these riders happened to post the nastiest pics on singletracks.com.
Grand Prize
Goo uploaded this one and the judges noted the serious wear on the crank teeth along with the dirt and grime that’s been built up over many, many rides. We know this didn’t happen all at once - shame on you Goo At least now you’ll have the proper Tri-Flow products to keep your equipment in tip-top shape plus a new Titec Hellbent Nemesis saddle!
First runner up
ckdake clearly knows where to find mud on the trail and the amount of gunk lodged between his wheel and seat tube is impressive. Aside from the copious amount of mud (which should easily wash off), the judges noted the dryness of the chain on the left side of the image. In honor of this epic mud slog, ckdake wins Tri-Flow Citrus Degreaser PLUS a Titec Honcho Prolite seatpost.
Second runner up
We had a tough time choosing the third prize winner but in the end, BFD squeaked by with this sad entry. Sometimes a MTB drivetrain can get so clogged the rear derailleur just gives up which is what we assume happened here. I wish we had some mud flaps to give away as a prize but BFD will just have to settle for some sweet Tri Flow Citrus Degreaser.
Calling these bike lights “Ultra” is an understatement. There really should be a warning label on the box saying “DANGER! Do not look directly into the light as permanent eye damage may result.” After fully charging these monsters I plugged them in, lightly tapped the switch, and POOF! I can’t see. OK, so maybe the label would just be for people like me
Light & Motion introduced the Seca 900 Ultra bike lights (MSRP $699.99) this year for the serious rider and XC marathon / 24-hour racing crowd. These lights come with six Cree R2 LEDs which are the highest rated LEDs available anywhere. And as if it wasn’t enough to have six R2s in this lamp, Light & Motion also designed a very high quality reflector to efficiently direct and sculpt the beam pattern to maximize light output (this is key and where other lights fail). The Seca 900 includes a nine cell 11.1V Li-Ion battery capable of tossing out 900 true lumens* for 3.5 hours of run time on the high setting. Other settings include medium (450 lumens for 7 hours), low (250 lumens for 14 hours), and a flash setting that will run for 100+ hours.
The included Multi-Chem smart charger uses the ultra-efficient Delta temperature method of charging. This method basically monitors the temperature of the battery over the charging cycle to ensure that the battery gets both a full charge while not overheating. And it does the job in just 3 and a half hours.
The graphic on the right shows the test data for the Seca 900 and you can see that it produces more than the advertised 900 lumens. Actual light output during testing was more like 953 lumens but for sake of honesty and accounting for possible production variances Light & Motion keeps the rating at 900 (besides, Seca 953 just doesn’t have the same ring to it). You can also see most of the light is in the light-blue to white area of the spectrum which keeps everything as bright as possible.
Light & Motion uses a custom array to optimize and maximize the light pattern for night riding. The Seca 900 features a gem shaped beam that’s flat on top and converges toward your tire in a V-shape. Extra light converges toward the center of the beam for maximum distance.
Installing the Seca 900 Ultra literally took less than 5 minutes on my bike. The handle bar mount is a one-handed breeze: simply loop the light through the mount, stretch the strap to secure it on the hook, and adjust the angle. In setting the angle you’ll want the outer pattern to just touch your tire with the lower edge of the spot about 20 feet in front of the bike. Installing the battery was a matter of simply feeding the strap through the adapter slots, slipping the battery into the adapter, and strapping everything down securely.
On the trails I have to say these are by far the most powerful set I have tried. These lamps toss so much light it’s literally like riding in a perfect bubble of daylight. Even when the terrain got bumpy or required a lot of steering, I felt very comfortable thanks to the light intensity and pattern. I found I could go as fast as I wanted without fear of missing a root or obstacle in the shadows. The video below shows me on a pitch black trail with no external lighting. The only light in the video is coming from the Seca 900 which basically has about as much power as a nuclear reactor. Notice how the light illuminates the trail even when cresting bumps!
The Seca 900 system also includes something called “Race mode” that allows you to quickly toggle between low and high intensity light settings for climbing and descending (respectively). This means fewer clicks to get to the two light modes you really need during the race!
Overall I can honestly say if you can afford to spend the extra bucks on this bike light, you will not be disappointed in any way. With the Seca 900 Ultra you’re getting a superior product with incredible battery life and leading on-trail performance in a svelte, easy to use package.
If you don’t think your riding isn’t quite up to the level of the Seca 900, consider giving the Stella 300 Dual a try. At half the cost of the Seca 900, this system is a bit more affordable and provides enough light to navigate dark trails with a good degree of comfort.
* One lumen is defined as the amount of light produced by a light source that emits one candela of luminous intensity over a specified angle. This is a more consistent way of measuring output rather than using Watts.
Maxxis is a name in MTB tires that needs no introduction. The company has been around for over 40 years producing high quality tires for almost everything that rolls, especially mountain bikes. This time around I tested the Maxxis Ardent 2.4 (MSRP about $50) which is one of the newer, large volume tires for the freerider / trail rider.
The Ardent is categorized for aggressive trails and medium to wet conditions with an emphasis on cornering control. If you look carefully at the photo below you can see two rows of very sharp and aggressive side knobs which will really grab and hold your line through the corners. Featuring a 60 TPI casing and 60a rubber compound, these tires will take rocky abuse and should last a long time.
Installing the Ardents along with a set of the Maxxis Freeride tubes (26x 2.20- 2.50, 1.2mm thick) on my Mavic Crossmax SX rims (removing the tubeless valve stems), took very little time at all. In fact I spent more time gathering the talcum powder and necessary tools to remove the valve stem than actually installing the tires and I didn’t even need a tire iron. The job took about 5 minutes per tire to dust up the tubes with powder and slip the Ardents on the rim (minding direction). Inflated the tires to 40psi and I was off.
I decided to take the tires to the 3-stages trail which is right next door to two great spots - Blue Mountain and Kolapore. 3-stages features a run that’s about 1km of just winding downhill with tight and twisty turns, lots of rooted sections and rock gardens plus tight singletrack which provides a great cardio workout. Basically 3-stages is the perfect place to put these tires through their paces!
Climbing with the Ardent tires was pretty awesome, especially considering this is meant to be an all-purpose tire. The aggressive multifaceted center tread really keeps this tire going in almost any type of terrain, grappling at everything and propelling the rider forward. Even getting caught up on rooted sections going up or down didn’t sway this tire’s progress. Likewise, the stable casing and tread really kept this tire pointing in the desired direction without any hints of wandering. The tough casing also helped absorb the abuse of step descents without a hint of trouble even when barreling through rock gardens and rooted terrain. This tire is like a laser with exacting tire placement on demand.
The Ardents really made me feel comfortable in the corners and I quickly learned to trust them when hitting the turns hard. With tons of grip and absolutely no squirm, I never even felt the tire roll when I was threading my way through tough rock gardens.
While the Ardent tires will run comfortably on nearly any trail surface, they really shine on terrain that is slightly on the softer side of things. I found that the great traction the Ardents offer drops off a bit when hitting dry hardpack or dust over hardpack. The tire basically seems to push more when it encounters hardpack and in these conditions it gets just good traction - not great. Hitting rivers and muddy spots was a no-brainer as these tires shed the gunk and kept moving along, ready for more.
Overall I gotta say the Ardent is one of my favorite tires in this size category. They are not uber-expensive, they wear well, they’re super stable, and most of all they offer tons of traction. These tires are like the stability control system on a Porsche Turbo: they make anyone look like they are as good as an F1 driver. I wouldn’t hesitate in recommending these to anyone who loves to ride.
My overall impressions:
9 out of 10 for climbing
9 out of 10 for rolling and efficiency
9 out of 10 for loose conditions
9 out of 10 for cornering
9 out of 10 for stopping in a straight line

When I started riding back in the early 1990s, there was basically just one flavor of mountain biking but today MTB categories can get a little confusing. I found this helpful chart over on the Turner website and I think it does a good job illustrating some of the divisions you’ll find in mountain biking find today. The arrows and text below the chart were added for the purposes of this post.
Right off the bat you can see the spectrum of riding from XC to Downhill and everything in between. Notice how the plot gets higher and more jagged as you move to the right, representing technical difficulty (not necessarily climbing or aerobic difficulty). It’s also cool to think of this as a progression chart - beginners can move from XC to AM and beyond as skills improve.
I really like how this chart can be used to show ranges rather than discreet points along the spectrum. In this particular chart, the shaded green area represents recommend usage for the Turner 5.Spot. Notice how it isn’t just a Trail or All Mountain bike. Based on the geometry and travel (5.5″ rear) this bike works well for XC, Trail, and AM riding.
The spectrum approach is also helpful for classifying riders. Most of us enjoy a variety of terrain and saying someone is strictly a Freerider or Downhiller usually doesn’t tell the whole story.
But wait, this chart has one more trick up its sleeve! Most mountain bike trails themselves can’t be readily classified into one type or another. A mellow XC trail may have 5 foot drops in places or even a freeride area that’s 5 miles into the trail. Other trails may have short bursts of All-Mountain style terrain with XC-type fireroads connecting sections. In fact I imagine some trails could cover the entire spectrum from XC to Downhill while others fit more neatly into a single category.
Some generalities about mountain bikes can be made from this chart and I’ve added arrows describing just a few trends you can expect to see when purchasing a new mountain bike. As you move from left to right, travel (front and rear) should increase while weight will follow roughly the same trend. Price, on the other hand, isn’t so easy to classify. For example, remember this $7,000 XC hardtail from Interbike? Finding a DH bike that costs half that amount wouldn’t be too hard (nor would finding a DH bike costing 50% more).
Now, if it were possible to create a mountain bike that could cover the entire chart from XC to DH that would be the holy grail. Maybe the Cannondale Simon will deliver on that dream one day
XC riders looking for a versatile tire for the fall riding season, listen up! I recently tested two of the five sets of XC tires from Intense Tire Systems (ITS) in a variety of conditions and I’m finally ready to share the results. I chose the System 4 and System 5 tires for my tests but you’ll want to choose the System series that’s best for your local terrain and trail conditions.
System 4 and System 5 tires are great for those will experience a wide range of weather and also for those of us who pack a few extra pounds. Both tires are 26 x 2.25″ and have the same single-ply casing with long lasting and grippy C3 rubber compound. These tires are true 2.25-inch wide tires which means they are higher volume compared to other brands (meaning fewer pinch flats for heavier riders). Both the System 4 and 5 tires can be had for about $45 a piece.
The System 4 (left) is an all-conditions tire designed to do equally as well on soft surface as well as hard pack. The ramped and chevron tread patterns work together to keep your wheel where you want it to be. The System 5 (right) is designed for softer terrain with its mud-shedding, wide-spaced tread pattern.
I found that both sets of Intense tires mounted easily and seated nicely in the rim with a satisfying pop. As always I recommend adding a bit of talcum powder to the inside of the tire before placing the tube to reduce friction within the tire and to increase performance. After inflating both sets to 40psi, I was pumped and ready to go! (get it? )
First up: the System 4 tires. I decided to try these guys just after a good rainfall at a local trail that has a great mix of terrain, small climbs, and a few low spots. That day the trail had it all: freshly dried hardpack, wet spots, and even a little mud. On hardpack the System 4 did well and I couldn’t help but compare the performance to the Kenda Small Block 8s. System 4 offers great control on hardpack and rolls smoothly with little energy needed to get them moving. Leaning into corners there was very little squirm and they tracked well, allowing me to change lines at will without fear of loosing traction.
The large volume of this tire really opens up terrain possibilities beyond smooth hardpack. Riding over rough obstacles like rocks and logs felt quite comfortable, especially compared to other 2.00-range XC tires I’ve used in the past. With a smaller-width XC tire I would normally run the risk of pinching a flat, but with these I am glad to say did not have a problem. For that reason, this is a good tire to consider if you find yourself pushing the clydesdale line.
In very loose, wet terrain the System 4s did manage to clog a bit but luckily I had another set of tires in my quiver: the System 5s!
Changing over to the System 5 tires and hitting the same trails on the same day really gave me a good perspective on the differences between these two sets. The System 5 tire ran with a bit more vibration, but didn’t show it when the terrain turned soft. Just like the System 4, the System 5 ran with decent efficiency and didn’t suck up too much energy to get things rolling. The System 5 tread felt stable - not overly soft - and did great job at preventing wheel spin during climbs. However, when the terrain got extra muddy, the System 5s still clogged a little and slipped at times. On the descents these tires offered a ton of control and showed great stopping power.
With the aggressive tread pattern you might think these tires would squirm in corners but I always felt comfortable leaning into the soft stuff. Now on dry, hard surfaces you might not want to lean into these as much; instead, keep the bike more perpendicular to the ground for better traction. Like the System 4 tires, the added air volume was great for trudging through gnarlier trails that might normally serve up pinched tubes.
The System 5 is another great tire, especially for this time of year when the trails are a bit on the softer side and logs and rocks can be slippery and wet. Of course if the trails are really wet it’s usually best to stay off them - lets conserve the trails for everyone!
My overall impressions: System 4
8 out of 10 for climbing
8 out of 10 for rolling and efficiency
7 out of 10 for loose conditions
8 out of 10 for hardpack
8 out of 10 cornering
