    Do any of you run 1x11 or 1x12 on your 26er?

    I was wondering if any of you had clearance issues with the derailleur on a 1x11 or 1x12 setup on your 26'ers.

    I have a Shimano 1x11. Run a 34 tooth with a 11-42 cassete. runs great.....no issues. May have topend issues if you have skinny fast tires on the road, but that is it.

    The 1x groupset mechs are the same length more or less as the old long cage mechs for 3x groupsets, clearance isn't an issue.

    1x's have been in use on 26ers for years, now. I'm guessing most use them and they've never been a problem. I've had 2 26ers with 1x11 and my son has a third. But when you ask about clearance issues, clearance from what? If it's the ground, I suppose the 1x12 would be a slightly bigger issue, but I doubt it's a deal breaker.

    I may be wrong, but can't you use a shorter cage on a 1x, Vs. a 3x?

    I figured the 1x11 and 1x12 would have a longer cage than like a 9 or 10. I have 2x10 and have hit my der a few times coming close to big rocks and roots.

    The Eagle derailleur is HUGE, and it does hang down quite a bit compared to 11 speed SRAM derailleurs.

    Upgraded my wife's 26 to xt 1x11 group recently. Used medium cage derailleur. Works flawlessly unless she were to back pedal while on 42 tooth cassette ring. It will jump down a couple rings. Because her frame is so small, the angle is a little too extreme for back pedaling on that particular ring. Hasn't been an issue at all, though. She never makes it to that ring. Don't think that would happen on a larger frame spaced properly.

    I just rebuilt my 26" hardtail this year with a full m8000 XT 1x11 setup. It's been 1x9 since 2008.

    No issues. No backpedaling-chain-drop. Works flawlessly with a 30t 104bcd chainring and 11-40 XT cassette. Geared really, really low. I could go with 32 or 34 chainring and still be fine IMO.

    Yep, 1 x 11 on my 26" Titus Motolite. I run some 4mm spacers between the crank spider and the chainring though to improve chainline.

    There is no change required in cage length between 8,9,10,11 speeds. They're just a number of cogs. Its the variation in tooth sizes that determine the cage length. Wrapping a length of chain around 9-42t is going to be different to 12-34T. It is this part that is relevant to cage length.

    If I don't make an attempt, how will I know if it will work?

    Depends on your legs / lungs. I've been running 1x9 since before it was cool. Since before narrow wide chainrings and clutch RD's.

    I was pretty accustomed to pushing a 32/34 gear combo. Moving over to the 1x11...I decided to do a 30t 104bcd chainring mixed with the 11-40t cassette because an 11-40t shifts smoother than 42 or 46t. All that with short 26" tires gives me some gear ratios that can seriously climb a wall. If I had gone with an 11-46 cassette, it would be seriously crazy low!


    I think if your drivetrain is worn out, it would be worth it to bump to the 1x11 instead of replacing old 9-speed stuff. That said, I'm considering moving my entire 11speed XT drivetrain over to my Stache where I really need the help.

    Why do fat-bikers consider the 26" forum a valid place to participate experience like this? The question is all related to tire circumference. A 26x5 is like running a 29+ on the Stache which has no bearing on the question being asked.

    A fat bike is not a 26er.

    Beg to differ, 26 inch rims. Dude. Same bike I run 26x 2.5" and 26x 3" It was a drivetrain question. Retro grouch.

    Hehehe, no name-calling. I'm not a retro grouch at all. I just bought a 29x3 and love it.

    I just installed GX Eagle on my Maverick and the RD cage does hang pretty low. However, the same group on a 650b bike would only yield around .75 inch in additional clearance, so no matter what there's not a lot. I doubt it'll be a big issue.

    I used to have a 3x8 setup on my '97 Bontrager. Rode it with a mountain bike club really hard trying to keep up with those carbon 29ers and broke a few teeth off of some of the chainrings. The chain was stretched and it wrecked to cassette so I went onto JensonUSA and got a RaceFace narrow wide chainring and shimano xt 11-42 cassette, shifter, and derailleur. Works great and have had it on there for the last 800 miles of use. Only had to replace the chain once a couple weeks ago. Highly suggest converting to 1x. I run it on all three of my bikes now.

    ive been 2x9 on my giant reign for years, finally stepping up to 1x11 with a oneUp 32t oval chainring and Box components 11-46 cassette. XT crank and XTR shifter/derailleur. Im excited to feel how it rides. worried I might want a larger chainring. I normally ride in my larger front gear, not sure how many teeth. I should check, but only drop low for steep climbs, also most everyopne i ride with is 27.5 or 29er so it gets hard to keep up until the downhills and tech sections

    I had a 1x11 SLX 7000 on my 1999 Headshok, worked fine before I got rid of it. The 1x, I mean. 2x is so much better.

    Just came across this thread and am a bit confused, are you guys saying that a 11speed cassette will fit on a setup that currently has a
    9 speed????

    Yes, 8,9,10,11 (Shimano) use the same freehub. 11 speed SRAM uses their XD driver, and 12 speed I assume too.
    So if you're running nine speed you could go to Shimano 11 speed if you wanted.

    Fit, yes. Function...you'd need an 11spd shifter and an 11spd derailleur to match. And none of the xd cassettes (SRAM higher end) so best to use Shimano unless you want a new hub/wheel.

    I get it I/we will require sifter, derailleur, new chain.. I'm just surprised the 11spd cassette will fit on a 9spd configuration, I guess the rings are as narrow to make it fit....
    I was under the impression 10spd was as far as we could go without replacing hub/wheel.....lots to think about now as I wasn't ready to switch my 26 to 27.5....this is a bonus
    Thank you

    ^^^Yep, that's pretty much it. No worries. The only downside is the chainline is really not that great on some bikes. Personally, I have yet to get on board with the 11spd stuff with all the great 10spd stuff out there. Currently running a 10spd 11-40 Sunrace with a 30t up front and an 11spd SLX 7000 rear derailleur. Works great!

    I'm assuming the Sunrace 11-40 is working out well???
    That's what I was thinking of switching to.

    What year is your Reign? I'm riding a 2008/2009 Reign X with the dual ring setup and I would love to ditch the extra ring, shifter, and derailleur. A lot of my friends have upgraded to 27.5 bikes and I'm getting smoked on the uphill. I have it built for gravity but would like to try out 1 x 11 setup.
    I smile because I have no idea what's going on.

    Go for the 1x11 setup, you wonít miss that front derailleur at all.

    xx1/xo1 on both of my hdr and sb66. Think about the 12speed if you would like the extra range. You do loose one or two climbing gears with the 11 speed.I have tagged the der a couple of times, but they have held up. I also tore the 9speed xo der off of my Palomino a few years ago too, so probably not the 11speed der fault.

    I almost did order 11spd stuff already, but I'm still thinking a bit, Zee chainring is 34T, I'm going to use most likely SLX 46T cassette, but even with that I'm loosing bit of low end, currently have 22/36T as lowest gear which is 0.65 while 1x setup I'm planning is ~0.74.

    BCD 104 limits a bit here, Zee costs only around 12$ which I find reasonable.

    Cheap Chinese oval narrow wide is only ~6$ for 32T but probably it will be just humorous value in use.

    So chainring cost is going up to around 50$ to get narrow wide of proper quality and 104BCD, replacing cranks is going to cost a lot as I'm still using square taper.

    30T SLX chainring would be quite inexpensive, but I guess chain will drop quite a bit with 2x or 3x chainring as single?

    I might just bite the bullet and try with 34T, that would mean I loose two gears from the low end, maybe it just will be good for my fitness to push harder.

    RD is second challenge, how do I mount direct mount RD to hanger type, I need some part I guess? I could not find anything from Bike-Discount, but then again I don't know name of the part either.

    Parts I'm planning to order:
    ZEE Chainring FC-M640/M645 34T (I'm going to slam that to my old Alivio crank)
    Shifter SLX 11-speed Rapidfire PLUS SL-M7000 right
    RD SLX 11-speed Rear Derailleur RD-M7000 GS Shadow+
    Chain 11-Speed Chain CN-HG701 with Quick-Link 116 links
    SLX 11-speed Cassette CS-M7000 11-46T
    Gear wire

    Total would be for those 190 euros and I really would like to stay 160 euros or less, but I guess not going to happen.

    What thoughts you more experienced ones have about this, any issues that I have not realized?

    I run a 1x9 w 32t in front for my 26er for a few years now and don't feel I need more - your mileage may vary. I run 1x11 on my tank downhill 650b and 29er. The only real difference I can tell is that the 1x9 shifts a bit rougher than the 1x11 - likely due to time in use and technology.

    2008 SX Trail 1x11

    I just finished this build.

    2008 SX Trail II

    Atomlab Pimplite hoops laced to Hope Pro 4 hubs
    32T Hope chainring
    11-46 Shimano XT cassette (the dinner plate)
    XT derailleur
    XTR chain
    XTR shifter
    SLX cranks
    Saint bottom bracket

    Both Fork and shock are Pushed with the Big Hit tune. I replaced all the frame bearings and the Avid Code brakes are freshly bled with new pads.
    Continental Trail King up front, Baron on the rear. This is a new-old bike that can take a pounding. It is considerably lighter than when new, but I haven't weighed it cause I really don't care.
    Sorry about the crappy pics....

    If you do get to weigh it, let us know. I have a 2006 version, built up lighter than stock. They were overbuilt from new, but really are great bikes.

    Also, back on topic...I just put an e-thirteen TRS+ 9-46 cassette on my 26" SC Chameleon that's got an 11-speed M8000 group. I had to sand the bushing on the cassette just a little bit to get it to clear a seal on my Mavic hub (the wheel bearings were binding otherwise), but it now works like a charm. I could've used the seal that Mavic provides with the XD freehub body but it's sized for the opening of a SRAM cassette; there would've been a gap with the TRS+ cassette that would've allowed dirt/muck in easily.

    That probably doesn't make much sense without pictures, but I'd have to pull apart the hub again to get 'em now, so, uh, sorry.

    I run an 11-42 11speed matched to 34 chain ring, gx long cage derailleur on a 2008 stumpjumper fsr and no problems, no need for extra gears.

Currently running a 10spd 11-40 Sunrace with a 30t up front and an 11spd SLX 7000 rear derailleur. Works great!
    I have on my 26" Turner 5Spot the Sunrace10 speed 11-42 cogs with an XTM8000 medium cage mated to an XT 10-Speed shifter and works great also....XT crank with Race Face 32 green chainring
