Ah, see i beg to differ. Given my understanding XX1 runs the same 1:1 actuation, i.e. cable pull distance = rear mech movement distance, so when paired with a 10speed 1:1 shifter it should operate identically to 10sp rear mech. Granted there will be minor adjustment with the b-limiter to ensure you dont have jockey wheels knocking on the 11t inner, but theoretically it should be functional!
Thoughts?
In reference to getting a bigger top end gear if i'm spinning out 32t x 11t combination down single track i would be quite content with my speed of 40km/h on a 160mm AM bike! for XC race scenarios, yes agree completely could probably push a 36t front with 10x42 rear!
