    Does anyone have any experience with e*thirteen’s 1×11 TRS+ 9-46 cassette (the “Eleven+”)?  With 511% range it sounds pretty nice.  I got a little curious about it, reading the YT article that Greg posted yesterday.  Sounds like a good alternative to SRAM’s 1×12 Eagle, especially for someone not getting a new bike but looking to upgrade their drivetrain at a reasonable cost … … especially someone like me who is still riding around on a 3×9. =)  Any thoughts about ride quality/performance?  Any thoughts about converting from a 3×9 drivetrain?  I have an 2012 Ibis Mojo HD.

    @mongwolf: Going from a 3X9 to a 1x is a big jump and will take some getting used to. I am going to venture that you have a shimano freehub so moving to any wide spaced cassettes (11-12 speed SRAM) will require buying a new freehub or building a new rear wheel. Leaving the standard freehub on you can do a SRAM NX group which will give you an 11-42 cassette. The e13 still requires an XD driver. If you want more range without changing your hub out you can go with a Sunrace 11-50 cassette . This will pair with your existing freehub. You’ll need a new shifter/rear derailleur/chain and a narrow/wide front ring. Ideally I’d recommend a 32t oval from Wolf Tooth or Absolute Black and if you have a 4-arm 104 spacing crankset you can get this one on the cheap. Lastly, I am dedicated SRAM fan and while these “hacked” set ups will work with Shimano shifters/derailleurs they are much easier to set up with SRAM. I’d save the money and look for either an NX or GX 11 speed set up. The NX is generally the cheapest, but works great and you will not be able to tell a difference between it and any other levels. Finally, if all this sounds like too much to putz with, then spend a little more and buy GX Eagle.

    Thanks for the input Sweets.  Lots to think about.  I’ll do a little background reading on what you have suggested.  I ride a lot of big backcountry in Mongolia and CO — lots of big climbing and earning the descents.   And I’m not a powerful climber, so I need as much range as I can get.  The 32t on front sounds right for me.  I might even try a 30t.  Thanks again.

    No problem toots. If you want massive range you could do the aforementioned with a 2x up front. Something like a the 11-50 cassette with 34/22 up front would be huge and I know some riders who do the giant mountain climbs at altitude have gone this route. Might be overkill, but you could always switch back to a 1x thereafter.

    I would definitely agree. The trs+ sounds cool but at some point the jumps between the gears are just too big. If you are willing to shell out a little cash, the GX-eagle would be your best bet. It has (almost) the same range as the trs+ but one more gear to give ya more options. Also one of those fancy e13 cassettes are $240 plus you need to get a chairing etc, where as gx-eagle is $375 for the whole setup! Also it you wanted a more budget option NX or SLX are good bets too.

    Hope this helped!

    Shredder, where are you seeing $375 for the GX-eagle group set?  I am seeing right about $495 online?   Still it is getting much more reasonable from the original price of like $1400 for the Gold.  If it is $495 now, maybe by next Black Friday we could see the set for around $395 or possibly $350.  I’ll be looking.  =)  Yes, good point on having too few gears for cadence and smoothness of shifting.  It sounds like smoothness is not an issue for this e*thirteen, but some are saying you are giving up a little noticeable amount of choice for cadence.  For some, that is probably not an issue.  For people like me, who are not powerful riders (i.e. wimpy legs =) ), that definitely could be an issue.

    @mongwolf: You can find a full GX Eagle kit for $350 on eBay from multiple sources. This doesn’t include a crankset, but you only need a narrow/wide chainring. I have XO1 Eagle on my bike, but run an inexpensive X1 crankset with a Wolf Tooth oval 32t ring and a GXP bottom bracket. If your current crankset has 104 spacing (most mountain crankset over the last half dozen plus years do) you’ll be all set.

    Thanks Sweets.
