I recently bought a Mongoose Status for my fiance. When I first received the bike, one of the bolts on the standard Promax disc brakes, which is not adjustable, is permanently touching the disc. So I exchanged it (Amazon) only to find a similar issue where the bolt is not touching, but it is about 0.5mm if not less from the disc. Has anyone ran into this issue, or is this just a terrible design flaw from a department store bike?
