Using the 18T center and 37T front & rear pulleys, I replace the rear belt and rear belt 18T pulley at the same time about every 20-25 5-minute runs/qualifiers/races. You are pretty much wasting your time if you do not replace the rear belt 18T pulley with the new rear belt, IMO. Also, I set my rear belt tension ONE NOTCH looser than the supplied sheets show. For some reason, the front belt and front 18T pulley last ALOT longer, probably a 2:1 ratio to the rear belt & center pulley.
