    XX1 Wear Issues?

    Like to see how many miles some of these components are getting before they need replacing.

    I just had to replace my front 32t ring. 1000miles. The teeth show a ton of wear and I started having chain drops.

    I'm at 250 or so with no wear on the chain and the teeth/cassette looking beautiful. 2, 6 hour races and some training rides.

    The chain and cassette seem fine. I put a the new chain ring on and its back to normal now. Competitive Cyclist even warrantied the ring. (Love those guys)

    I was riding up a sharp incline and in too low of a gear. Hammered real hard and busted a link. I had a master link with me and repaired it on the trail. I'm still usin that chain for practice, but not races.

    Just spent much of Sea Otter talking to more than a dozen XX1 users, none reported any problems and all were more than happy after months of use. Anyone else out there with issues? Has SRAM been contacted?

    I had clicking sounds coming from the rear derailleur and had to take apart and grease after a few rides. No problems after several hundred miles. There is a thread on the issue. Called Sram and they were no help.

    Explain what you greased. Was it a knocking noise?

    I have about 1000km (625miles) on my XX1 and have broken 2 jockey wheels. Very hard to get parts.

    Chain has now started to drop off as well but most of the first half of my riding has been in very wet and gritty conditions.

    Cut my chain about 10mm too short initially (didn't set it up for maximum chain extension on sag) and broke a few locating screws as well.

    very fiddly to get right.

    love it very much but should it be this sensitive?

    My X0 and XTR has never been this problematic and delicate.

    anyone else had jockey wheel problems?

    If your chain was initially too short, this may have damaged the jockey wheels, causing their premature failure.

    Maybe?

    yes it was like a knocking noise and I thought it was the suspension, but found out every time the suspension compressed I would get the knocking noise. In the stand you could get the bike to make the noise by just putting a little pressure on the chain. I took the clutch apart and greased it and have not had any more problems. Here is a link to the thread XX1 knocking/clunking

    I have to lube it with a little oil at the frame mount and the jockey cage pivot every few rides to keep it quite. It works fine just makes the noise. Not real happy after spending 1,000 on the system. There is a problem with the derailleurs and Sram does not seem to know how to fix it. I think it does hurt Sram's sales as when riding in a group riders ask me what that noise is and I tell them it is my 1,000 xx1 system and who wants a noisy system. The Sram brakes I had on to different bikes made noise and always needed to be adjusted and I would never buy them again. Do they even test this stuff?

    XX1 Wear Issues?

    I love the XX1 system, but it has been wearing very quickly for me, most notably the chain ring. 280 trail miles and it was toast. I started to get a very bad grinding noise which caused me to look closer. I'll post some pictures later. My lbs got SRAM to warranty the ring, but they won't do it again. I'll just go to the new race face rings. SRAM did tell my shop that due to my weight and riding style (225lbs and all mountain riding on a Stumpy EVO) it didn't surprise them it wore so quickly. I beg to differ and expect my chain ring to at least last a full season.

    Isn't accelerated wear (and reduced weight) part of the equation with the XX line (1X11 or 2x10)?

    My chain ring is already showing signs of wear after 10 miles. I would expect this after 100 miles. The derailleur has also started making some noise. Yay.

    650 miles, cassette is done and chainring is showing significant wear. Cassette has one broken tooth, and looks like teeth on most cogs are worn to nearly a hook shape. I assume this is not how they should be, but I'll compare to the new cassette when it arrives. I have also already replaced the derailleur due to breakage. Interestingly the chain shows very little wear, and I've been known to replace chains multiple times per year with other systems. I use Rock-n-Roll blue lube after every ride and wipe the entire drivetrain very clean, but I haven't used a chain cleaning device. Also, the protective covers on the crankarms are peeling off and look like sh!t.

    Man you are hard on the equipment! I have never seen a tooth off a cog, but I guess it happens. $400 for a cassette...ouch!

    What terrain are you riding?

    Sounds like you are doing the right maintenance, not sure what else you could do. I'm quite sure the clunky derailleur is not helping.

    It's been ridden on Pacific Northwest single track, a dozen or so short track races, one XC race, and one enduro race. I don't generally have a lot of drivetrain issues. Don't get me wrong, I am still not sorry I went with the XX1, but the durability so far is not what I would have expected.

    I'm not disappointed with 1X11 at all, just SRAM design/QC. Never had issues with my XTR drive train. When Shimano decides to release XTR 1X11, I'm outta here!

    Not intentionally, but after reading it again, it does sound like I was being a d1ck. My fault.

    I guess what I was trying to suggest is it possible that the current rate of wear on XX1 components consistent with the XX line which by design aren't meant to last as long as say X9 or X7? I know a lot of people, myself included, are stoked on the 1x11 but are waiting for it to hit some of lesser lines for a savings at buy-in and lifecycle.

    It will be interesting if 3rd party vendors like WTC and others are able address this with their replacement rings. Heck, maybe even X01?!

    i have about 600 miles on my XX1 and it grinds like mad in the largest 3 or 4 cogs when under load. i am pretty much positive it is either the pulleys and/or chainring causing the noise and vibration. i replaced the chain two rides ago as it broke. i run a 34t chainring and it shows wear, but not more than i would expect. grinding seems to get louder as more dust and dirt accumulate. any ideas here? thanks.

    I've seen a few bikes with excessive chainring wear. Sram warrantied the rings. I'm guessing the extra friction from the narrow/wide spacing on the rings is causing some quicker than normal wear.

    To increase the life on your chainring you can always rotate them "One hole over" that way you have fresh new teeth in the part the chain pulls..

    thanks for the feedback. Ended up trying a new ring last night and what do you know? Grinding is gone. I am going to try to get it warrantied too. The rotating and even reversing is a great idea, but SRAM in their quest to block 3rd parties made the bolt pattern in such a way that you cannot rotate or reverse the XX1 ring. Or maybe they did it to increase sales of replacement goods? Either way it is the one disappointment i have with an overall fantastic 1x experience. Thanks again!

    Not to mention, the chain can only go on the ring a certain way.

    I feel like I'm lucky. I'm close to 2500 miles on my xx1. I rotate chains every 800 miles or so to be safe, and plan to shoot for 2 rotations each through 4 chains. Chain ring still works fine, though there is some visual wear on the "wide" teeth. I'm even running grip shift and it has held up. Only complaint is the cassette gets noisy if you don't keep the interface with the free hub clean and greased.

    XX1 Wear Issues?

    Not much luck for me. I put a new chain and chainring on after 1000km because the noise was driving me mad. New chain slips on the 42t. Complained to SRAM via my LBS and they gave me a new chain and chainring, without any apology or explanation. I complained further about the cassette and they basically said that I must be doing something unusual and they're not interested.

    So stuff 'em. I'll move to a 1x10 shimano setup when the 36t dies. Seriously not impressed with SRAM. 1000km on a REALLY expensive cassette is completely unacceptable.

    I broke a chain at .70 on my park tool and with about 577 miles and was overdue to replace the first chainring at that time. Now to put it in perspective as these are 577 miles that include a lot of sustained fire road climbs and i am about 265 lbs. I run a 34t up front as i like to have a better top speed for the flatter sections and for pavement getting to and from the trail. that said i find myself in the larger 4 steel cogs of the cassette most of the time. Being the 42t is aluminum i avoid that like the plague, just like i did on my XX or X0 cassettes. simply for emergencies only. lol. anyway, the chainline of the XX1 is set up to be spot on in the 5th smallest cog, so not even in the middle of the cassette. i speculate that is because it would drag and hang up more on the 10t & 12t cogs if the chainline was in the middle. i am sure there is a little more science behind that, but it is what it is. All of that said, i spend most of my harder torque time cross chained and therefore wear the outside of the chainring faster than the inside and pull harder on one side of the chain than the other. This time I plan to turn my chain around or rotate it (outside to inside) at about 350 miles and see if i can get more life out of it. I am trying a 34t race face narrow/wide ring this time to see if i can get more life out of it too. i may even rotate the chainring at 350 miles too since you can do that on the race face. Worst case i go back to the 32t up front and stay in the middle of the cassette more of the time and i am sure i will get a lot more life out of the chain and ring. All of this is simply speculation or theory, but seems logical to me. I still love the simplicity and have no regrets with my xx1 group.

    I have had XX1 on my Intense Carbine since April '13. I havent had to replace any of the parts yet but have come to the conclusion that the system must be kept clean to avoid feeling and hearing a grinding noise when climbing or with the cranks under a strong load. I think the tolerances are much tighter. If the front chainring and/or the R. derailer pulleys are not free of grease/dirt then the whole system seems to run a little rough under load. This isnt that big of a deal unless you are lazy when it comes to cleaning your drivetrain.

    I got 1500 miles out of my first XX1 groups chainring (32t). Then I flipped it over and it worked flawlessly for another 200 before I replaced it prior to selling the bike. (Chain replaced at 750mi and 1500mi)

    I only got 250 miles our of my 2nd XX1 group's chainring (30t), I flipped it over and ran it backwards until the replacement arrived from warranty. Again, it worked flawlessly flipped backward (inside-out).

    Both rings started grinding when worn...they grind because the teeth are so much taller than a standard ring, a pocket wears into the base of the tooth, and the chain kind of goes "over center" into the pocket as it meshes with the ring.

    On my XX 1 set up the "grinding" noise is a non-issue as long as the chain and chainring (Wolf Tooth) are clean. My thought is that the clutch on the Derailleur (keeps tension on the chain) along with the wide portion of the chainring create some noise. Overall, the drive train has been excellent. I did break one of the first Gen chains (one with the hollowed side plates) but have had no issues with the new version. I do plan to try a KMC 11 speed chain next as I have always found them very reliable.

    Built the bike Feb. 2013. I have just over 1900 miles on my XX1 group.

    Issues: Broke real derailleur with stick - no warranty - bought new to replace. No problem.

    Replaced chain 12/05/13 as it was time and things went bad from there. Because the big rear ring is aluminum and not steel like the other rings its fried. Chain jumped and skipped on the big ring and a basic grinding noise in all the other rings became apparent. LBS called SRAM, explained situation, SRAM warrantied the cassette. Said it should not happen that soon. (But SRAM rep also said two chain replacements requires a new rear cassette!) Happy - Happy - Joy - Joy!

    (I'll admit, being in the beta group of this product has been, and should continue to be pricey.) Got the new cassette and the big ring skipping and jumping stopped but the overall grinding sound did not. Going to now replace the front ring with a Wolf Components ring.

    Otherwise, I have been happy with the performance of the XX1 as a whole. Just not the dependability. SRAM had to know this as I am SURE they had to test this group for more than the 1900+ miles I've done.

    Think I am going to move onto the Rohloff SPEEHUB when the SRAM falls apart completely.

    this is for an X01. .9 of chain stretch at under 500 miles, have not contacted Sram, intend to. Replaced chain, shifting is good. Agreed on the keeping clean, as well I have oiled the moving pieces on the derauiller as well, with out it gets grindy. have been using dumonde tech original
    Go that way really fast......if anything gets in your way turn.

    Anybody have any broken chainring teeth. Maybe 200 miles on on the 1 x 10 setup with the xx1 ring and just discovered a broken tooth. Have no idea how long it's been broken but I'm still not dropping chains. Warranty?

    I had the grinding chainring noise too after approx 500 miles. I flipped it around (wolftooth) and the noise disappeared. Something about the size or shape of the teeth makes it grind badly when they get worn.

    I posted this in another thread but what would be nice is for someone to make a "reverse spider" for GXP, BB30, Hollowgram etc. XX1 Chainrings.

    Sram have designed a ring that cannot be rotated by 1 tooth and not easily run the other way around.... Currently you CAN run the ring the other way around on the stock spider (to extend the life) but it's not ideal - the chainline is off and there are mud ledges and it doesn't look so good.

    So how about a 3rd party reverse spider? You would buy this additional spider once and it would allow you to run all of your worn XX1 chainrings the other way around, maybe double the life of them.

    The solution you seek pretty much exists today and works very well actually. I solved it by using a traditional 3x spider and a race face narrow wide ring. I get more mileage from the race face tooth profile and then I can flip it around. Hell of a lot cheaper too cuz race face rings are less than half the price of the sram rings. Just keep that to us forum members though as we don't need race face raising the price!

    Goodoljake: Thanks. I actually just measured the chainline with the chainring flipped (on a Leonardi Hollowgram spider) and it's exactly the same both ways, which is great as the reports of low chainring life and grinding noises was worrying me but now I should at least be able to reverse each ring to double the life. Mine actually almost looks better reversed, as the Leonardi spider is all black too.

    Interesting about the chainline. It would make sense to me to have the chainline further over towards the larger rear cogs, as that's where the higher torque pedalling would usually tend to be. However, we need to avoid catching the chain on a larger cogs teeth when cross chained to the small cogs, as you said.
