I'm upgrading my hardtail to a new 9 speed XT drivetrain and am having problems with the front deralliuer. The deralliuer I took off the bike was a 31.8 which fit perfectly. The one I am replacing it with is a "one-size-fits-all" deal with shims to get it to 31.8 and 28.X but the medium shim (for 31.8) makes the clamp far too small to accomodate my seat tube. The small shim is even further off and without a shim the clamp is too large. The directions were fairly clear by Shimano standards--simply put the metal plate inside the plastic clip and clip them on the inside of the clamp. Gray (m) for 31.8 and black (s) for 28.whatever.
Has anyone else had this problem or am I just too stupid to figure out how to use the shims?
