I wanted to ride the Cervelo P2 so I went to the local crit course and did some 1 min on/off power intervals. I'm trying a lower bar position, about 1.25 centimeters lower than my Giant TT bike. One problem I had was the I left the bars too long so I really had to reach to get to the bar end shifters. Corrected that after the ride. Have to admit that I've never really done any training on a tt bike. I usually just show up at the first tt maybe having ridden the tt bike a couple of time prior. I definitely don;t get that big burst of power that I can on the road bike. The numbers weren't great but neither was my position. I'll work on it some more. Power was mid to upper 400's as opposed to 520 avg on the road bike.
