Suppose an TdF rider swapped the groupset of his pro bike from Dura ace mechanical to tiagra. What would he notice?

And please note, Im talking about a pro rider, not you. :smile:

Why less gears????
Tiagra 10 speed, DA 11.

Professionals spend so much time on their bikes and near or at maximum performance level that even the most minute changes become apparent. Things like 2psi above or below their preferred tyre pressure, for instance.

A longer lever throw. If they've got large hands or long fingers they might ever prefer that.

Aside from that, and the obvious lack of a cog, I doubt it would make a single seconds difference.
