Insert spindle, do not use that 10-12mm spacer, attach the drive side and then go back to that knob thing on non drive side to remove play. That knob is called preload adjuster and is the solution to your problem.
    Thanks, but without the spacer there is still play even with the preload adjuster knob at it's maximum extension.

    Then 10-12mm thing is not a spacer but an elastomer to preload the bearing. Look at the instructions above. Are you using a mallet to tap the drive side on? Are you torquing to correct level?

    The piece I am referring to is the piece illustrated at the base of the yellow arrow and i believe it is metal.

    Well, just so happens that I will be in your area tomorrow afternoon and will take that defective crank off your hands for $25. Deal?

    Haha! In my area huh? Nepal? They actually got it fixed without any machining! I honestly have no idea what they were doing wrong, but it works fantastically now. I'll take it out on a real trail ride today, but there is a fairly steep hill(paved) on the way back home from the bike shop and I was carrying my 2-year-old son on my back. I never had to use the lowest gear. Super smooth, easy shifts, even under load.

    Why? Mine works great, so does the set of RobRobideau (see post above) and muzzanic and I can name a few more...

    edit: nice pics on your blog Rob!

    Got in a 1.5 hour trail ride with the new drivetrain and it works like a dream. Exactly what I was hoping for. Even while bouncing down bone-jarring rocky paths like this, no dropped chains or even chain slap.


    @betzel Glad you enjoyed the pics!

    After >80km, I lost the chain for the first time and it was my own fault. A half-inch-diameter stick found its way into the drivetrain. Here are a few pics of it mounted on my Chinese carbon 29er hard tail.

    Rob, that's cheating and doesn't count as losing a chain in normal conditions. No, just kidding, seriously...I don't read something was damaged so lucky you! Would be a pity if you had to change de RD already....

    You are right, it definitely doesn't count and I am blessed not to have any damage to spokes or components!

    In the past sticks have been the death of RD's for me, XX1 construction seems much sturdier, which direction did the chain suck in the woodwork (did it go through RD or not)?

    I don't know exactly what route it took, but it ended up trapped between the spokes of the rear wheel and the rear derailleur. It took quite a bit of twisting, wiggling, and finagling to get it out. The rear derailleur had to have taken a decent hit.

    Got this funny little question that's been tickling my head for the past couple of weeks:

    What is Rotor going to do about XX1? Are they going to be able to come out with an elliptical Q-ring that will hold the chain on without a guide like SRAM's?

    I guess there are both practical and patent concerns to think about. Will Rotor (and/or all the other chainring manufacturers) be legally allowed to copy the tooth design that makes the front of XX1 so special?

    I have a fair amount of time on a chain (since mid August) and it is doing just great. I am pretty good about cleaning it quite often but it has seen some abuse too. Since there were not many of these chains in early going, this particular one went through World Cup finals, training, Olympics, more training and World Champs then on to my bike for some more abuse and Iceman. Continues on today

    Sram does say it is their strongest chain they have ever manufactured. Time will tell. Building up my new Trek Superfly 100 SL this week with a new group. Can't wait to get out on it even if it is in the snow!!!!

    I've been considering this drivetrain for the past few days, and I'd like to thank all of you for this enlightening thread !

    However, there is one question whose answer I can't find : could I go from a 28t chainring to a 32t without changing the chain ? Assuming that my primary chainring would be a 30t.

    Yes Just. I have been told that it can cover 4 teeth difference. I haven't fitted my 28 yet but use the 30 & 32 with same chain no problems .

    In the grand skeem of things even if you couldn't what an extra chain.

    I had the same question. I'd want a 36 or 38 tooth ring. So I'd put one of those on the crank, fit the chain and then keep the 32 around in case I go somewhere hilly or buy a 29er.
    These chains are supposed to last so if you did switch rings you could keep the old ring/chain combo together in case you switch back.

    Very true, not having to switch chains would just be less effort

    For that matter having 1 bike with 28 tooth & 1 with 32 tooth rings would be even less effort

    Thats if you don't count the extra effort it would take to make the money to pay for it.

    I talked to Rotor Ring a month ago and they said they weren't planning to make rings to fit XX1 cranks but I didn't specifically ask if they had any plans to try an alternating tooth thickness ring. I don't remember hearing if Sram patented it.
    I can't imagine they how much they would charge for and alternating tooth thickness rotor ring. I'm a Rotor Ring fan and am going to go XX1. I'm having a tough time deciding if I'll keep my current rotor ring and run a top mount chain guide or run the XX1 crank.
    If I can live with the 33t front ring instead of a 30t I'm leaning toward sticking with Rotor.

    32 with12-34 soon to be 34 with 11-36. Can do everything i want on it from amateur XC racing to all around trail lollygaging. Couldn't be more satisfied within losing the front derailleur, shifter and two chain rings. Do it!

    I was told a 2 teeth difference in both ways. So if you run a 30t chainring you can ride 28 and 32. But maybe 4 teeth difference will work also if I understand you correctly? I'm waiting for my 28t (riding 32t now) and have a second chain for it.

    And I was also told at the LBS that the chainlock can be used more often than once. But only with the same chain. When using a new chain you should use a new lock.

    I think any crank/chain ring manufacturer can make a taller tooth profile, right? I know the SS cogs and chainrings are already taller by a smudge. You can't patent chain line or Q factor I'm pretty sure so these mfg's can make whatever they want.

    I had no problem switching between a 32 and 34 on Emily Batty's bike, but when we went to 36, it was too short. It was originally sized for a 32 though so if you size it off your middle sized ring, I would bet it will be fine.

    I bet also, once you start riding with the 10-42, you will not need to switch the ring much. I live here in Colorado and have only found the 36 is needed for me. 34 was a little small when having to connect downhill paved stretches and I have not found anything I need smaller than the 36/42. If I can't make it on that combo, I am probably walking anyway I have done some super steep climbing with it and 4 hour rides in the "hills" here- pretty good for me. If I knew there was no super fast downhills/road riding stretches, I would probably run the 34 though. Everyone is different though, but I suspect most will not need more than 2 different rings in their arsenal

    First ride on my 1x10 setup with XX1 cranks and chainring today. I have to agree 100% with the folks who have mentioned how quiet the drivetrain is with XX1.

    The new drivetrain + my silent XTR brakes made for the quietest ride as far as bike noise I have had.

    North Shore Billet is planning to produce aftermarket spiders for XX1 rings. This is good news for me - I have some XO cranks that I would like to run a XX1 ring on.

    I get it, that's how racing and teams and being a pro goes...

    I just wonder how soon before Shimano has their top riders on a similar 1X system, of if most Shimano pros prefering the 1X will just used chainguides/11-36 cassettes.

    just looked through Hope pro 2 evo specs on their site, concidering the trials/ss hub bodies are the same, wouldn't that hub work with the XD driver too?
    or am i wrong?

    Unless I'm missing something, their trials/SS hubs are different than their geared hubs. The SS/Trials hubs have a hub with symmetric spoke flanges and a freehub that is about 30% shorter than the geared freehub.

    I'm also interested, so I sent them a mail and got following response :

    Hi, we are working on a new design matching this groupset, but honestly, there is no release date so far.

    The quesion whether or not a chainguide would be needed was not answered.

    That's cool as an alternative, and it says they will be thicker to "help" with keeping the chain on, but still they don't have the special teeth that the Sram does. Possibly patented.
    No it never stops hurting, but if you keep at it you can go faster.

    You are referring to the NSB chainrings.

    I was referring to the blurb in the article that says NSB is also working on a XX1 *spider* so you can use XX1 chainrings on XO or X9 cranks.

    I'm not sure if anyone else is having the same issue as I, but so far I hate this thing on my Tallboy. I went on a single ride after transferring the XX1 from my Highball to the Tallboy and I'm already planning on going back. While peddling up the first uphill climb in 2nd gear I noticed a popping sound coming from the rear wheel area. The sound was traced back to the rear derailleur pulley arm. It appears as though the "Type 2 clutch" is popping every time the suspension is compressed near half way, or less. I followed the chain install direction to the tee, fully compressed suspension plus a link. Hell, I even added 2 more links once I found the cause of the noise. The noise is most obvious in 1st through 4th.

    I'm really hoping that others have had this same issues with some type of resolution. The noise/feeling really has me not wanting to ride the bike. It just feels like something is loose within the suspension and makes riding it very annoying.

    Sram's New XX1 Group

    There are several threads on the type 2 clutch popping issue in the drivetrain forum. Not just an issue with XX1 from what I read. I have two T2 XO derailleurs with no issues so far. Hoping they don't start popping in the future.

    I ran an X9 Type 2 derailleur for last half of last race season ... far and away the best rear der I've ever had on a bike, zero issues! Running mine on a f/s Jet9.

    Yep, definitely a common problem full suspension users are running in to. It's back on the hardtail and works great. It's a shame because my initial thought when purchasing the set up was to have the flexibility of using it on either bike. Oh well, at least not a total loss.

    I'll wait and see what Shimano comes up with. At least I have the ability of adjusting the clutch on my XTR Shadow.

    I know quite a few people running them on Jet9 RDO's & Rip9's for a while now with no problems.

    Both bikes are known for not having much pedal feed back over bumps.
