Derek, 1. Someone wanted a better chainline, and adjusted it so. 2. The BB shell face was milled, and it was adjusted so. 3. Some one wanted to hide some spare freewheel spacers. Steven Johnson, Shiloh, IL
there are TWO shims between the fixed cup and the frame. I assume the thin
one is a standard "washer" but the other one is 2-3mm (about 1/16") thick and
is apparently there to shift the spindle to the right (chain side).
Other than clearance (chainring-to-chainstay), is there any reason for
such
a spacer?
