Just occured to me when i was watching floyd today, zipp don't make a PT disc wheel, so does he not use the PT computer, i don't think i saw it on his handlebars. Franky was saying he TT's around 400-420w (holy ****), so does he just practice the course with the PT wheel and then just use the same gears and cadence during the race, and that along with the time check's is how he pace's himself? Or do you think he just does it on feel?
