Descent Roglic (Tour de France 2017, stage 17)

Strong piece of work by Roglic, his escape and win in one of the toughest stages of the 2017 Tour de France.

Some technical remarks on his descent:

Steering too much from the shoulders, body center of gravity (saddle) too far to the outside. Therefore he is wringing a bit and he is regularly drifting out the curve. It seems that at the end of the curve, he has lost a lot of speed.
Also he takes the corner early, he goes to the inside early, so the corner gets longer/rounder and therefore he comes out too wide.

This despite the fact that the descent of the Galibier is quite easy.

Remarkably, the commentators are talking about ‘fantasic descending skills’ and ‘an absolute terrific decent of the Galibier’. Perhaps it’s a matter of language, they speak more in superlatives. In any case, I do see his decend differently.

Interesting is an interview in which Roglic was asked whether his former career as a ski-jumper had offered him an advantage for descending. Yes, with regards to speed (up to  100 km per hour). But no further was his answer.
For ex-skiers, you often see that their cornering technique on the bicycle seems to benefit from their former carreer.
