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!
I'm just a garage mech. Nontheless, I've worked on all sorts of bikes. I'm a proponet of scarfing to make fit, but do nice job. There are longer reach brake caliper out there but they are not high end....just my 2 cents....use the force!!!
My wife rides a 5200 47 cm WSD with 650c wheels. Let me do some checking and I'll get back to you.
edit: This is a 2003 model. The brake caliper is polished aluminum and says "Shimano Ultegra", nothing about "SL". The brake pad fixing bolt is close to the bottom of the slot and the pads do not touch the tire.
Thanks Al, that's the exact year/model of my wife's - the Ultegra SLs are new ones I just picked up, but the reach should be the same. I'll go snoop around and see if something else is making it come up short like that, but there's just not a lot to go wrong there! Weird.
