I have a set of Alex wheels for training and a set of Velocity Escapes for racing. My brakes are the Paul Neo-Retros (mafac style). With the training wheels I don't get any squeal or chatter but with the Escapes the front screams like crazy and chatters uncontrollably. The bike is a Specialized Crux (aluminum) so I'm guessing it would just be worse with any other fork. Any idea what could be causing this? Fixes?
