- MCMark C.Verified BuyerRated 5 out of 5 stars2 months agoXT - enough said!
My SLX derailleur has been playing up for ages so new needed and why not make it an upgrade to the system. Paired with Hope jockey wheels, this is now dreamy!

- ACAnnie C.Rated 5 out of 5 stars3 days agoPerfick
Fit the best, fit Shimano
- KAKarl A.Verified BuyerRated 5 out of 5 stars2 months agoreplacement
spot on
- IHIan H.Verified BuyerRated 5 out of 5 stars2 months agoTougher than Deore
What's to say? the Deore version has a cage made of cheese and the crash I had would have wiped out a wireless mech I think so got another XT Tor replace one. The cable routing a little awkward and b tension thingy me flaps whilst fitting but once on XT is maybe the level to start at in Shimano range.
The clutch assembly can be accessed for cleaning and greasing if needed but no other work possible, then shimano is like this so I was happy to see the clutch part accessible. same size allen key for stops and b-stops is good
