I have a new frame that I am building up. I was going to use the old Hayes mags (160 rotors) I have (I think G1 caliper) but I always had some rub and fading issues w/ them on the last frame. I know that they at least need bleeding, pads and one line shortened with the good possibility of a larger rotor for the front and a new one for the back. With all this I maybe at the same cost of new set of 2007 185 bb7s. (excluding levers and cable). What should I do?
