nah, he can't take Phinney.
Phinney last year in Copenhagen, did a 1'01" kilo. His 4km split was
1st k 1:08.953
2nd k1:03.982 (2:12.935)
3rd k 1:01.699 (3:14.634)
4th k 1:00.589 (4:15.223)
look at that progression. Phinney will be able to get on top of a much larger gear than Bobridge. And he can take it out faster, as evidenced by his 1'01" in Copenhagen, and his runner up, in the Poland World's where is also pulled out a 1'01".
Go to G in the finals at Manchester, if he held up his schedule, he was on for a 4'13" mid/high ride
Geraint Thomas
final:
1:07.132 (2:09.411)
1:02.279 (2:09.41)
1:02.171 (3:11.582)
he caught his pursuit finalist Cornu.
Very good chance he would have come home with a sub 1'03" final km and a sub 4'14", somewhere mid to high 4'13".
There is no way Bobridge will beat those guys, and he will never beat Phinney, he just can't match the power, and the gear size potential that Phinney has. But his race weight, at the Tour de France in say, 5 years, he will be around 62/63 kg, he will be competing for GC. Phinney can't. Thomas might get down to 69kg, which is less than Wiggins, and he is faster than Wiggins on the track, so add it up.
