Shims + Front Derailleur
I bought 2 used xt front derailleurs for 5$ at the annual sale at the Lehigh Valley Velodrome. I want to put them on a frame i bought, but one is too small and one is too big. Is it possible to shim the clamp on the bigger one to make it fit, or do i need to shell out 20$ for a lx that actually fits?
Thanks
