Horrified by the fact that I am not going to be able to afford race wheels this year I’ve decided to do something drastic, and quite possibly fool-hardy. I’m going to try and make my own race wheels. For the rear I know I’ve heard before about how J-disc and accel use somesort of rubbery compound and heat shrink them over their wheels, what is this called? I just can’t seem to remember. Also, has anyone ever done this before? Any tips. thanks.
