My roadbike has a mix of components. It has shimano claris r2000 fd and crankset and everything from sti's, rd and where all for 10 speed. The problem was when Im on any 3 small cogs on the back and I shifted my fd to the small chainring, the chain would not engage fully and I always ended up spinning the cranks but not transferring any power to the cogs. I hope that you guys can aid me in my woe.
