Okay now we're seeing improvements. Once again the yellow
outline references the baseline position. This is Chris riding with
coaching from me on head position. With this advice, he's saving
around 15 W at 40 km/h.
Chris reported this position was slightly harder to maintain,
therefore I advised he work on this in training and especially
indoors on the turbo trainer. Muscles that are being called upon to
stabilise this posture are just like any other muscle, they can be
strengthened. Therefore this position will become easier to
maintain as muscle strength and stability increase.
Certainly this is easier than training a threshold increase by
Chris does find times when he's riding in the basebar, either on
the ramp of a dual carriageway approaching a turn, or on hillier TT
courses. I wanted to identify the threshold at which the
aerodynamic advantage of riding in the aerobars is outweighed by
the easier climbing position:
