Can’t rate the Middleburn RS8’s highly enough, always been super reliable, and their customer service excellent.

Cheers George — bearings are coming from them anyway so will ask for one of those too.

Has anyone on here attempted a DIY bearing change on a Geometron/Nicolai (G15)? It all seems quite straight forward, though I’m struggling to work out how to pull/push out the pivots from the main linkage.

I seem to drop a chain 3-4 times /ride… Running a middleburn TT 10spd with Sram x9 clutch mech, and little chain keeper.

Have found it very frustrating – It seems like the thick part of the ring can still fit into the thin section of the chain, so wondering if it’s only really suitable for 11 speed?

Amazing, thanks crispedwheel
