Any Trek Mechs - Rear Caliper Question for 650C Frameset
I'm building up an older but unused Trek 5200 WSD (OCLV) for my wife, and ran into a weird problem last night when I started putting it together. This is the 47cm model that used the 650c wheels. The issue I'm having is that the Ultegra SL calipers come up just a bit short in the rear and fully extended sit right on the top edge of the rim. If they slip or twist even a little she's going to cut the sidewall, so it's not going to work.
Did these framesets require a long reach caliper or something? I may grind the slot a few milimeters to elongate it, but I really hate to do that to a beautiful new brake!
