I have a trek 4300. I just recently bought bontrager 700c selects. I take em out of the box and realize that the brake pads will lock on the spokes not on the rim. Is the wheel too big for the bike even if I change to a disc brake set-up? also a friend looked at them and said these wheels are not ready for disc brakes. Also I have like 1 1/2" between the rim and the frame. (rim without tire) what can I do? I really like these wheels but I don't want to buy another bike just for the wheels?!?!?!
