Time Trial / Time Trialling / TT

I just came across this image, which i'm going to plonk here because i think its interesting. (sorry if a repost)

Shows how big the difference is between Wiggo and Andy. Would be interesting to see a similar comparison with Wiggo, Fab and Tony Martin or other top testers.

Wiggo has bigger thighs, Andy has more arse. These promote different crank-pelvis relationships which influence the range of efficient torso angles.
