Sram sx ........bobbins
Discussion
My bikes are all Shimano and my tandem is Rohloff.My Trek Roscoe however is Sram SX and can I get it to index correctly,can I bugger.No problem going 12- 1 but 1-12 skips every other gear,as soon as I get on to properly ride everything skips.
Where am I going wrong,or do I need to start from scratch,baring in mind it has only done 20 km since it left the shop new.

Sram SX.
ThisJust spend some time getting it to index properly, follow guides on the internet. Be patient with it
I have problems with Sram NX on my stumpy, the chains slipped off that many times ive ruined the paint on my frame
I would never buy anything sram again, including their s
t brakes. Sram 12sp stuff seems to be a bit of a lottery at best. Not that 12sp in general has proven the be the easiest thing to live with for anyone.
My GX set-up lasted 3 months before it decided it wasn't going to play along anymore and no amount of new chains, mechs, shifters, cables etc would fix it.
I junked the lot in favour of 12sp XT in the end, I don't dare tempt fate by saying it's any good, but in the 6 weeks I've had it so far it's been perfect, but so was GX at this point.
SRAM has been making 12sp MTB groupsets for nearly 5 years now, and I don't know any owners who haven't pulled their hair out at least once with them. I'd hope Shimano stuff will be more robust, SRAM seem more occupied with bigger and bigger cassettes than actually making it work well.

I found the OEM SRAM SX/NX combo shifted ok but if swapping wheels with a slightly different cassette offset (miniscule) I needed to re set up the RD including the gapping of RD to cassette cogs correctly or as I found to my cost the RD and cassette meshed with the RD loosing that battle and snapping at the pivot. replaced with the next best SRAM RD (SX/GX?) and adjusted /gapped as per guides , shifted nice but wore out in under 4 months and stopped shifting. Now running a Shimano 12spd shifter/RD (XT) on the SRAM cassette, fiddly to set up (ghost shifting mid cassette was problematic until sorted) but working fine now.

Are you using the correct cables - most bike shops fit Shimano cables as a default which have slightly larger diameter - which completely screws with shifting. I have 3 bikes with SRMA (10, 11 & 12 speed) all are faultless.
It’s a Trek bought from the Trek shop at Handforth so they should be able to get it right.Gassing Station | Pedal Powered | Top of Page | What's New | My Stuff
