Giro TT Bikes

OK, I missed most of the coverage, so maybe they explained it, but why wasn't Di Luca using aero bars ? Reminded me of Fignon in the TdF without them when Greg had them. And why wasn't everyone using some degree of aero wheel ?

But botto, its a time trial! How absurd that anyone would enter a time trial on anything other than a TT bike!

Dennis Menchov.

First.

Those rims are almost box-section.

The course was tough but at speeds of 40k/hr TT gear would have helped a lot. DiLuca was dumping time and anything over 14mph would be benefit tt gear.

But Menchov had good position on the bike which counts for a lot.

Who else didn't use aero bars ?

I'm just surprised that aero wheels weren't more common. I know they have a bit of a weight penalty, but the high end ones are still pretty light. With a solo ride I'd think the aero benefits would prevail.

Flying down those "hills" with a TT bike would have been dangerous.

Menchov did have clip ons so that counts as aero.

Right. There were plenty of straight sections where getting on the clip ons would have had to have provided an aero advantage. I cannot fathom why Di Luca and others wouldn't use any advantage they could. Di Luca still finished in the top 10. Impressive.

He needed nut padding for his aero tuck.

Here is the idea on not pushing aero on this tt I think:

1. There is so much climbing and that light weight bike and wheels are significant. Aero benefits of slow speed climbing are minimal but weight is critical. Road bikes are typically lighter, and so are climbing wheels.
2. The descents are so steep that the aero advantage is largely uneeded and the improved road bike handling is more important.

Correct.

If Levi didn't have a TT bike, it wasn't called for. Take that to the bank.

Not much argument that a road bike makes sense on that course. It's the lack of clip-ons that seems odd. Missing out on the chance to go aero when the road permits.

I'm very disappointed that the bf.net spreadsheet mafia hasnt yet calculated whether di luca should have ridden a tt bike

please dont make me open that wattage board to find out what bike di luca should have chosen!
