What is rodriguez like in TT, don't know his form in that area?
One comparison this year is the stage 21 of the giro d'italia where of course Rodriguez lost the general classification to Hesjedal. 28km TT round Milan
The timings were
Pinotti
Geraint Thomas + 39s
...
6th Ryder Hesjedal + 1m9
7th Larsson 1min14
11th Stannard 1min 24
16th Taylor Phinney 1min 31
26th Rodriguez 1min56
by means of crap comparison (different courses, very different riders and at the end of a grand tour), the olympic TT a few weeks ago Froome finished 3rd
Taylor Phinney was 50 seconds behind him
Pinotti was about +1min1
Larson was 1min 47 behind froome.
Hesjedal of course did the TT but did a very slow one so I've not included his time. Also worth noting Phinney had a bit of a good 'un in the olympics. Larsson/Pinotti may be the best reference marks to the other riders we're concerned with here.
I'm sure someone else can come up with a better one.
P.S. if you do want another one both Westra and Menchov both rode the Olympics and the earlier TT in the TDF stage 9. As did Brajkovic for that matter.
