Single Ring/1×9 set up reliability
So back in July I started running 1×9 (36 – 11/32) on my XTC 29er. Idea behind this was save a little weight, less parts and therefore simpler, and also looks better.
Initial rides were great, and didn’t feel like I was missing the granny ring, or big ring.
However almost every ride there has been a mechanical in some way, snapper rear mech, snapped chain (about 5 times now) It’s starting to annoy me and i’m considering going back to 3×9 or maybe just 2×9, but there is an obvious cost associated with this.
Guess my questions is do others running a similar set up have issues? My thinking is that maybe i’m putting to much pressure through the drivetrain,and thus causing snapped chains etc…
I’m running a Hope SS ring, 11/32 deore spec cassette and a Sram PC951 chain and XT Shadow mech. Which was all new when I fitted it.
Probably worth pointing out that 2 of these rides were Mayhem and Sleepless so not ideal conditions, 3rd time was Kielder and the others have just been local rides.Posted 5 years agosimonbeaMember
I had that same SRAM Chain which is now hanging from my xmas tree in star shaped decorations. I only just learnt that when a chain snaps you shouldn’t fix it with the standard pins and links, my chain had started snapping every ride, I kept fixing it this way and it would snap again. Only ever use powerlinks to join a chain apparently!Posted 5 years agotraildogMember
Zero problems at all, infact far less which is part of what I like about a 1×9 setup. Set the chain length by putting it in the largest cog, cycling the suspension and checking that the mech isn’t pulled excessively. I’m actually running a short road cage at the moment because it was spare and you can on a single ring setup.
I found SRAM chains went terrible some time ago and have not used one since snapping one, which was long before I went single ring. I dont’ know if they improved again as I’ll not take the risk.Posted 5 years agorobinlaidlawMember
Assuming your bike is like every other full suspension design I’ve encountered and the chain needs to get longer as the suspension compresses, set the chain length by unbolting the shock at one end and fully compressing the suspension and then set the chain length on the big sprocket as tight plus 2 or 3 links.Posted 5 years ago
You’ll be suprised how much extra chain the suspension needs, it’ll be that that’s killing the chain I’ll bet.
Just remembered that KMC was the first chain, this was snapped at Mayhem and replaced with a PC951.
Been running this since, and when it has snapped 2 occasions have been powerlinks, the other just stuff it back together…
The very last time I bolted it back together just to get home! This happened 😆Posted 5 years ago
