basics yep, they didnt touch the high/low limit screws, b-screw, mech hanger was straight, absolutly every other gear shifted fine, it was'nt badly setup or user error as per every member above with the same issue, it just started happening out of the blue
its bizarre but i think the clean of mech itself has probably done it (including the spring etc)
As has been suggested above, older sram used to really suffer from springs going baggy and not getting into the smallest cog.
The problem/solution was to make sure you always put the bike away with the bike in the smallest cog, so it's stored with all the tension out the spring and it doesn't stretch as much.
On shimano now, but still do it as it seems like a good habit to be in.
cheers IA, never thought about leaving it in 11th TBH, thats not a bad little tip so thanks for that
its defo something menial that was easily fixed so yep you could well be right
will make mental note to leave it in that gear overnight now
Im a bit sad really, the one habit i have is i always clean my drivetrain, quick spray with GT85 on pivots and spring to get excess water out and store bike in smallest cog to keep all tension out of the spring.
That sounds like a faff but it really isn't. 5 minute job and i very very rarely have any drivetrain issues,
The rest of the bike can stay honking but i like my shifting to work 🙂
Now i am running X01 is seems that wee routine will definitely being carried on 🙂

This was my thoughts too when I first saw and used the "cage lock" feature of the newest mechs. It is a convenient feature to keep the cage out of the way of the rest of the mech with no wheels fitted (I have to store my bike with the wheels off) but I couldn't help thinking it introduced the possibility of creep in the spring. I always store the bike in the smallest cog and don't use the cage lock for any extended length of time.
Can I check you mean the 42 ring when you say 11th?
Mine is 3 months old and hasn't been shifting properly for a month or so. It was awesome brand new, stealth silent and crisp as you like. LBS have mugged up the tension on the cable but it's no longer silent and crisp. If I slacken the tension a touch the shifting is great but it will not stay in 42. Enough tension in the cable means the rest of the shifting is wrong, so this thread caught my eye.
I keep the bike clean etc, but what's the cure?
😆 how is the 42t ever going to be 11th gear?
1 to 11 goes down the cassette not up, anyways joking aside, nope it was the smallest cog on the cassette i had the issue with
ive never had a problem what soever with the 1st cog (42t), id suggest you check your b-tension screw, its absolutly vital to get this right or it simply shifts crap if its out
it needs to be circa 12-15mm from top jockey wheel to bottom of 42t in (1st gear) 42t
This is all new to me, be gentle!
I'll throw money at the problem and let my LBS fiddle with it, if you think about it, I don't know the difference between 1st and 11th, so how the chuffing heck do you think I'll cope with a b screw!
gonesailing, its worth figuring out for yourself THB. The SRAM techdocs have all the details. Plus its very easy to set up. Knowledge on how to do it is key though.
OW, i had a small issue like this for a while, but after every ride ill give the mech pivots a quick spray with GT98 and all issues gone. X01 s a thing of beauty 🙂
gonesailing 😆 sorry wasnt being arsey, just amused me thats all, but fair point if your struggling it is genuinely just worth taking it the LBS, my lbs set up my old x01 from new and it was absolutly precise! its just worth having it done there for a tenner TBH if your not confident
the b tension screw is absolutly the most important thing on x01 to get it smooth and once its setup right it should be sweet in every gear
mac - exactly the same, its about keeping the pivots/spring nice and lubed/sprayed with something to keep it moving, as above also helps if you store it in 11th cog when not using
i find if i havent (especially in shitty weather) washed/cleaned it for a few rides it does struggle more so than when spotless, but it still shifts better than any other gearing system ive ever used, just try and keep the chain/jockey wheels etc clean and its perfect
i still cant fault it, its just an amazing gear setup to me
After much frustration throughout this thread I think I might have cracked the 11th gear issues I've been having (touch wood!)
Full length outers 😀
The spring in XX1 seems so weak that even the minutest amount of mud or slightest incorrect cable tension would through everything out of whack. By eye it all looked and felt fine but clearly the smallest amount of grit was enough to disrupt things. Full length outers have made a world of difference!
Don't worry, my skill set is elsewhere and it's an easy mistake to make, in my head at least.
I've increased and decreased the B screw tension and it makes no difference, it will not go into 42T, or should I say it only goes in and stays in if I keep my finger on the shifter. Only cable tension works but then the other 10 are out of sync.
Anything else you can suggest as a quick fix or it's back to the shop for this fool?
That just sounds like a limit screw issue gonesailing. XX1 is very sensitive to this too- as in a quarter of a turn sometimes feels too much when fine tuning. A few of us also noticed that there is some play in the XX1 mechs so although you set the limit screw correctly for the 42T sprocket without the chain on, the small play in the mech pulls the top jockey out of line from the 42T. I had to set the limit screw so the top jockey was a fraction inboard towards the hub. Once the chain is back on everything lines up nicely. An odd quarter turn made a massive difference to the noise in the smaller cogs too, so although everything might look aligned by eye when you first set up the mech it is worth making very slight adjustments with the chain on.
I tried a little bit of that Dan, but I've decided to support my LBS and let a professional sort it.
If I play around too much I'll really mess it up, so I'll leave it for now, thank you all for your help.
gonna keep this thread alive, given i started it!
so no issues for me since the 11th cog issue, except ive suddenly not been able to shift down into 3rd biggest cog, shifts up fine, and shifting in every other gear is spot on, but 3rd has become really really really hesitant, it eventually goes in though but is a pain for climbing
so anyone else had this? a few folk have suggested its the cable, which is more than likely the case, but thought i resurrect this thread given the amount of xx1 users on it
definitely spring tension, have replaced cable and outer(full outer) all adjusted perfectly all cleaned but still wont shift to 11th cog. however if you just give it the slightest tug on the mech itll shift, maybe its time sram went with the customer and give us the option to fit a stiffer spring at the expense of light shifting. I ask this question though has the guy who tests the shifting got unusually week thumbs?????
After breaking and replacing a chain at BotB last weekend my x01 won't shift into the 11..I always store it in the 11 (old school rider) is it likely to just require a bit of a clean and lub on the pivots?
I really, really don't want to replace the cables as its an internal routed niner which means taking the bio-centric BB out and spending about 4 hours threading the cable....
