My Explosif came with two (mismatched) black plastic covers for the bosses. One of them fell off and got lost pretty quickly. I just leave them naked at the moment and try not to let it bother me too much...J-RAD said:If you are running discs. What did you do with the non removeable brake bosses? I know they make nylon plugs for the removeable ones, but do they make any kind of plug or cover for the ones on the newer explosif?
