100% Trials newbie. Bought a 30 year old Aprila. I bought the bike sight unseen, shipped to me. The brake pads are fine but the rotors are rusted. not 'surface'-rust that that I've seen on my road and dirt-bike rotors; much thicker. The rear in particular seems to work poorly. The seller assures me that this is normal. Dunno, maybe I'm making a to-do over nothing. Maybe strong brakes aren't expected on a trials bike. What do you guys say. Should I consider having the rotors turned.
