Just wondering if anyone has these with powertap. Thinking of buying some used 303s with powertap but wondering what I'd use them for. I obviously could use them for racing but I thought the best thing for powertap was training. I currently train on Ksyrium Elites since they are rock solid and then when I go to race and throw on the race wheelset (Eurus '06) I feel especially fast. Are people training daily on these Zipps with powertap? Would I be asking for mechanical problems and tire damage at 195 pounds and daily usage? the deal is pretty sweet but if I don't use the powertap for daily training then it's too much money for race wheels with a fancy gadget.
