I know these topics were done to death 5 years ago, but I have a bike to build before the weekend and need some quick confirmation on the setup I intend to build, and if it wont work have a little time to buy more stuff!
I think the rear will be ok,
XT 10 spd rear mech
SLX 10 speed cassette
XT 1- speed front shifter
XT 10 speed chain.
The front setup may be a problem
Sram x7 crank GXP – 39/26
Sram X5 10 speed double front mech
XT front 2×0 shifter
Will the XT front shifter work with the SRAM front mech?
Will the 2×10 SRAM X7 crank work with the XT chain and XT rear mech?
A one speed shifter won’t work with anything. Assuming you mean a double, I’m not sure but I would imagine it’d be fine – a double is pretty tolerant. I’d give it a go and buy a new shimano mech if you have problems.
The crankset will be fine with the chain and rear mech.
