to me, it would be a great power sensor..
1. my favorite pedal has been look for 6years (keo2max, keo carbon).
2. i own powertap sl2.4, but i would not use this PT wheel for race, because i liked to use the other carbon wheel.
3. i ride road racer when i train, but use cervelo TT bike for triathlon race.
so i think i would like to have it..
