Brake caliper/tire clearance?
How much min. clearance should you have between the brake caliper and tire? I have an old road bike that I just put on a new Mavic wheel and it has about a millimeter of clearance. If you take the brake cable loose and the caliper opens, it touches. When you squeeze the caliper shut and spin the tire, the new tire nibs hit the caliper. Too close? Thanks for your help in advance. ( I should add I went from a 23 to 25 .. thought it would work )
I might be asking the question wrong. It's the top of the tire and the underside of the caliper that I'm concerned about. I'm in the process of a restoration project. Right now, the calipers are on but, the cables aren't yet. If you squeeze the calipers shut until the pad just about touches the rim, you can spin the wheel and there is just enough clearance. You can hear the new tire nibs hitting but, the tire doesn't rub. There might be 1-2mm of clearance. Is that enough?
