I'm looking for suggestions on how to eliminate this. I've got a singlespeed w/ sliding dropouts. I recently changed the rear cog from a 16 to an 18 and had to add a link to the chain. In order to get enough tension on the chain, I have to pull the wheel back and its causing the tips of the polygon rotor to hit the caliper of my J7's.
Should I (A) dremmel the tips of the rotor or will this screw up the breaking
(B) put a couple of washers between the caliper mount and caliper or will this screw up the geometry somehow.
Any suggestions would be greatly appreciated.
