- 11spd SLX mech won’t work with 11-46 cassette – help!
I’ve just swapped all my kit over from a 26″ Rocket to a 26″ 456 Evo 2. I’ve had most of it set up on the 456 before, but whilst I’ve had the Rocket built up I upgraded from a 10spd 11-36 Zee setup to an 11spd 11-46 SLX. It worked fine on the Rocket.
On the 456 it doesn’t. With no chain on and the mech in the highest (11t) gear the cable pinch bolt is within a few mm of the bigger cogs. In the lowest (46t) gear the top jockey wheel interferes with the 46t cog.
Whatever I do with the B-limit screw seems to make negligible difference.
Has anyone experienced this? It looks like the mech is rotated too far back, but the tab on the mech is up against the one on the frame so I don’t think it can be that. There is maybe a tiny bend in the hanger, but I don’t think enough to cause this much problem.
No pics I’m afraid as I’m also having freehub issues and that’s also in lots of little bits.Posted 4 months agospacehopperSubscriber
I have had to use a spacer between the Mech hangar and the mech on an old 456 to get the gears to play nicely..
mech hangar was checked and perfectly aligned..
It effectively made the hangar a few mm thicker and moved the mech outwards..
with one setup, the mech was literally bottomed out on the spring with the limit screw removed and still wouldnt change into the 11T cog.. added the spacer… and it all worked fine.
might help a bit in your situation too..Posted 4 months agoPoopscoopSubscriber
OP, search out a thread I stayed early last year!
I was setting up a sunrace 11 50, 11spd drive train. Nightmare. Tried SLX, XT mechs to sort. Three types in the end!
Your problem sounds very similar…..
In the end a shorter cage xt mech AND using a tool to adjust the mech hanger for alignment cured the issue. It’s all in that thread. PM me if you can’t find it and I’ll have a go. 👍Posted 4 months ago
