    shimming rotor out - how far?

    hi, i have a juicy 3 brake which rubs the spokes of the front wheel. i understand i can shim the rotor out and move the caliper with it until it doesnt rub the spokes. my question is, how much of a gap should i aim for between caliper and spokes? not sure if flexing is an issue etc... cheers!

    Make sure your caliper is installed correctly first. If it is, most calipers have some lateral adjustability you can put in. If this is not enough, you may need to get your disc tabs faced a little to move the calipers outboard. Recenter the rotor over the caliper when the caliper is no longer hitting the spokes .

    Shim the rotor with the Syntace rotor shims (or similar) just enough for the caliper to clear the spokes. Since the Juicy moves both pistons (unlike mechs like the bb7 that move only one), the rotor won't flex much, and I wouldn't expect the caliper to flex much and never enough to hit the spokes after the rotor is shimmed.

    I wouldn't expect the wheel to flex as much that the spokes would "come out" and hit the caliper... if it did happen.. you could try with another shim, they are thin so you can fine tune.
