Was soooooo close to buying a wolf tooth lever for my KS Lev as a sign of appreciation to it last night then wondered if anyone had modded a shifter to do it. Found this:
and so today I took my spare XT front I spec B shifter and did the same to it. Feels a lot better than the stock control and integrates straight on the brake. Too easy. I have only just gone 1x10 and am wondering about how long it will take me to do the inevitable phantom left shift though...
