I recently purchased a second wheelset to avoid the pita of changing my tires. I'm fairly proficient at tire changing, but my Schwalbe Marathon commuter tires are very difficult to mount; a good excuse for another wheelset. Only takes me about 5 minutes to swap the wheelsets.
I have an issue with the rear caliper rubbing the disc on the new wheelset.
Frame is a Cannondale Caffeine, brakes are juicy 5's, rubbing wheelset has a DT Swiss 370 hub. Problem is that the rotor rubs the brake pad closest to the hub. I've gone through the usual Juicy5 adjustments: spread spread brake pads, loosen CPS bolts and center caliper. Doesn't quite work with the 370-equipped wheel; if the rotor were moved <.5 mm away from the hub, all would be fine.
I stumbled across Syntace disc shims. They're .2mm thick and have a shape similar to the cross section of a hub. Seems ideal for my situation.
I called a few LBS check availability. Both tried to steer me away from the hub shim approach. One recommended enlarging the adjustment slot on the calipers. The other suggested moving the caliper mount with thin washers. I would only take the dremel to the caliper as a last resort. I'm reluctant to shim the caliper mount since my original wheelset fits fine without any shims; admittedly if I could find thin enough SS washers it would likely work fine.
I'm not sure either LBS was familiar with the Syntace shims since both voiced strength concerns. I tried to explain it was a shim designed for exactly the problem I am experiencing and that I wasn't proposing shimming the six mounting bolts.
Are the Syntace shims the best solution for my problem?
