Has anyone tried a KMC 10SL chain on their Shimano 'DynaSys' 10 speed drivetrain? If so, how'd you find the performance?
FWIW, I've always used KMC 9 speed chains on other bikes, and have been v.happy with the results. However, I've noticed that my new (10 spd) bike has a directional Shimano chain, so am wondering if it'd be best sticking with Shimano.
