Yeti has just released a brand-new trail bike: the SB5c. Sporting 27.5″/650b wheels, this is a full-carbon rig with 5″ (127mm) of travel.

I’m sure the question that’s on everyone’s mind is: “is this Yeti’s answer to the controversial discontinuation of the SB66c?” While maybe this bike will help calm the crowd of agitated SB66c fans, the SB5c most definitely isn’t just a 27.5-wheeled version of that acclaimed steed.

For starters, with just 5″ of travel, this bike isn’t quite as long-legged as the SB66c. But the real difference is the never-before-seen Switch Infinity Technology.

Switch Infinity

Developed in conjunction with Fox, the Switch Infinity technology/linkage is radically different from most other suspension linkages on the market. While it is descended from the system found in the previous SB66c and the SB95, Yeti and Fox have taken things to a ‘hole ‘nuther level. Since the technical details are probably way over this poor journalist’s head, I’ll quote for you Yeti’s take on the tech:

Overview

 

Switch Infinity utilizes a patented translating pivot that switches direction as the bike moves through its travel. This provides excellent anti-squat characteristics for superior pedaling performance and ideal suspension characteristics as it gets deeper into the travel.

 

Efficiency

 

At the beginning of the travel, the main pivot translates upward, creating a rearward wheel path. This provides excellent anti-squat and optimum pedaling performance. While the pedaling is crisp, the linear leverage ratio and translating pivot combine for amazing small bump sensitivity. The linear movement provides unprecedented control of the kinematics and marks a significant improvement over link-based designs.

 

Control

 

Once the Switch Infinity system reaches the inflection point, the main pivot begins to translate downward. This linear movement prevents the chain force from adversely affecting the suspension performance and gives the suspension a controlled, bottomless feel.

 

Mechanical Superiority

 

The linear path of the patented Switch Infinity system has very little resistance as it moves through its travel. This allows the system to achieve seemingly contradictory characteristics. In the early stage of the travel it displays superior pedaling efficiency and excellent small bump sensitivity. As you move deeper into the travel, it is well supported and responds effortlessly to square edge hits. The mechanical advantage of our linear system cannot be achieved with traditional link designs.

 

Durable

 

The Switch Infinity is a simple, lightweight, bombproof system built by Fox Racing Shox from proven suspension components and engineered and tested to withstand the worst riding conditions. We only use the best components in its construction — Kashima coated stanchions for low friction and durability, seals and bushings that are used in Fox’s off-road racing division, and a lightweight forged translating pivot. We have field tested the parts for over three years and the original bushings, seals, and stanchions are still in perfect working condition. Fox has thrown the system into its testing regimen as well — spray testing, mud, dyno, and ride testing — and found the system worthy enough to be “Enabled by Fox.” The system is significantly lighter (100g) than the original Switch Technology.

 

Tunable

 

Switch Infinity is a versatile system easily adaptable to different travel platforms. The system can be mounted in any orientation and can achieve a myriad of kinematics depending on the design intent. For example, longer travel bikes require drastically different kinematics later in the travel (controlling wheel path trajectory). The Switch Infinity system can control this much more precisely than other suspension designs because of the linear path of the main pivot. We also can control leverage ratio and anti-squat with much greater freedom than other systems.

Now, if that happened to go over your head as well, be sure to check out this video for a visual demonstration of what happens throughout the travel range:

One thing is certain: if the paragraph titled “Tunable” is any indication, the SB5c is just the first of many Yeti bikes that we’ll see with Switch Infinity technology.

    Demo one…hell I want to own one! Now I can just sell my car to be able to afford it right?! Who needs a car anyway!!

  • delphinide

    Yeti’s new SB5c is cray crazy. Initial reviews say it climbs superb, and rides like it has a lot more travel. Definitely want to demo one!

  • GoldenGoose

    How much does the frame weigh on this? Seems like all that extra stuff would have to add some heft.

  • jkldouglas

    I think this has a good chance to be a high volume seller for Yeti. It is a bike for the masses: about 130 travel, 27.5 wheels, as well as all the other bells and whistles that other similar trail bikes have.

    If the bike rides as well as the precious SB platform it should be great. The only issue I have is the price. I think they would be well served to have a lower tiered carbon similar to what Santa Cruz did with its Carbon and Carbon C trims. It would really drive the price down and make the bike a little more attainable.

  • John Fisch

    I’m surprised they didn’t run this one with a bit more travel. With 27.5″ wheels and 6″ travel, the Santa Cruz Nomad and Intense Tracer are the hot bikes in the boutique brands right now. Yeti may have missed an opportunity here.

    I love the Tracer, but want a longer top tube–traditionally a hallmark of Yeti geometry. Woulda’ been nice to see Yeti go that route, especially since the 66 got canned.

  • jkldouglas

    I think the reason they didn’t give it more travel is that the majority of people don’t need that much. Enthusiasts like most of the people commenting love all that travel, but in the end companies sellore trail bikes than enduro bikes. While the nomad is a ‘hot’ bike, it probably isn’t a high volume bike.

    • John Fisch

      That makes sense. I did make a mistake, however. I’m not sure why I typed Nomad–the bike I had in mind was the Bronson, which SC’s 6″ travel 650b bike. SC can’t make them fast enough right now, and they’re selling far better than the 5010, which is their 5″, 650B bike. Intense is also really moving both Tracers and Carbines, both 6″ travel 650b bikes.

      Of course, SC and Intense remain firmly in the “boutique bike” category. I think the major players are, as you say, moving more trail bikes than all-mountain/enduro bikes. Maybe Yeti is thinking more like the big boys and less like their boutique background.

      Still I would have loved to have seen them put 6″ on a switch/27.5 platform. I’m sure it would have been glorious. After all, they put 5″ on the SB-95–it only makes sense to crank up the travel as you move down a wheel size. Especially since one of the selling points of the switch is its efficiency combined with bump compliance–if that’s truly the case, there’s no need to not give it some endure-level travel!

    • jkldouglas

      I totally agree with what you are saying. I really do think it is only a matter of time until we see a SB6c. Especially since Jared Graves is currently racing on a ‘no longer in production’ SB66. Unfortunately for 26″ guys, the downfall of the 66 was the fact that it had 26″ wheels when the hot new thing was 27.5. Regardless of wheel size, it is a great bike. So, I would be surprised if they didn’t release a SB6c within a year.

    • delphinide

      I agree. It is weird, but Yeti does weird things. That being said, they are not stupid and know what the market is doing, but it does take them a while to make a bike because they are such a small company. I agree with JKLDouglas that we will probably see an SB6c equivalent real soon, and expect the Infinity to replace the suspension on the 95 as well at some point. This is a bike for “the masses”, and based on what I’ve read, and someone I know that rode one here at Apex, it is a trail bike (plus) that when ridden by guys like Graves, will do well in the Enduro circuit. After all, in the end an inch of travel is insignificant if the rest of the bike is dialed and rides like it has more travel.

  • bravesdave

    It seems I remember a couple of other bikes with the switch type rear suspension/shock set up. Does anyone know other bikes which are using the same concept (different design of course)?

    • John Fisch

      They started with the SB-66 (26″ wheel/6″ travel)
      Then they added the SB-95 (29″ wheel/5″ travel)
      Then they added the SB-75 (27.5″ wheel/5″ travel)
      All with the original switch platform. This new switch looks significantly different.

      Then they deleted the SB-66. As the article in the link above noted, they couldn’t give them away on the open market–even though every guy in every Yeti shop I talked to said the -66 was their fave–and as JKDouglas noted, they still have a team racer using one.

    • bravesdave

      Thanks for the reply John. I was asking about other companies, not just Yeti. I didn’t make that clear. Yetis are pretty special bikes though for sure. I have test ridden a SB-66 and loved it. Nice bike.

      I’m still a 26″ fan, and I like the 27.5″. I can’t get into the 29er thing, just doesn’t float my boat on how they behave.

      All in all, I think it is great that consumers have a choice, even though I don’t like that production of 26″ bikes is decreasing. But the market is the market. and companies have to compete and thus make what they think the consumers will want. From what I’ve read, it seems the companies were the ones that progressively offered the different wheel sizes, and yet now, it seems they are somewhat concerned about 26″ sales. =)

    • John Fisch

      Dave,
      I think switch is Yeti proprietary, so I doubt any other bikes have it. They haven’t licensed it like the VPP (used by Intense and Santa Cruz) or the dw-link (used by Ibis, Turner and Pivot)

    • jkldouglas

      If I remember correctly, the “Switch” technology was the brain child of a separate suspension design conpany. Yeti then developed the technology with the 3rd party company, that I can’t seem to remember the name of, and got exclusive rights for three years as part of the deal. So Yeti bikes of the last few years are the only bikes with that specific suspension design.

      If you noticed, the new “Switch Infinity” had a Yeti patent pending number with it, which tells me that not only did Yeti improve the design, they did so enough to make it their own. So, from the looks of it you won’t see any non Yeti bikes with the switch infinity suspension design. That should really help them differentiate themselves from the rest of the market.

  • Matt Phipps

    Interesting that everyone seems to glued to the concept that an Enduro bike must be 6 inches of travel. Remember the larger the wheel, the less travel needed. Depending on the course and the rider, 5 inch travel bikes, like the Stumpjumper Evo are often used in Enduro racing. Particularly for riders under 185 lbs, as it has an identical head tube angle as it’s big brother, the Enduro, just 5.1 inches vs. 6 inches.

    • RTM

      6″ does seem to be the perfect mix though of light, DH capable and “pedalable” if I can get a 6″ bike at the same weight and geometry as a 5″ bike, I’ll take it.
