I have some un-mated stronglight 93 right arms (165 and 170mm), and I'd like to buy some generic left crank arms, but i'd still like to have a matching crank set. Is it difficult, or does anyone offer a service to increase the threading from 22mm to 23.15mm so that my 2 crank arms can be matched, i can polish and maybe reshape the left arm, put stronglight caps into both arms, etc., and sort of have a pseudo-matching crank set ?? I'm just curious, thanks.
