So I just scored a Masi track bike that came with a drilled, but not factory drilled, fork with round blades. The seller said that he's not sure if you can actually run a brake on it or not because the fork blades are circular and might not be strong enough to handle braking forces if you were to actually lock up the wheel.
Now if I were to actually be locking up the front wheel I'd have other issues to worry about. But is it true that round blades and brakes don't mix? I've tried searching but it's hard to find anything because all the terms are rather generic.
