What gear ratios do Tour de France Riders Use?

Watching the coverage of the Tour de France, I’ve been trying to get a sense for what sort of gear ratios the riders use when climbing hills, cruising, or sprinting. Does anyone know?
More specifically, I’m looking not necessarily for the gear ratios that are on the bike, but which they select at various points in the race. Do the riders stay in their lowest gear most of the way up La Bonette, for instance?

On a standard ride – it’s pretty normal: 53×39 and 11×23 10 or 11 speed. They change these for hard, high climbing days and for TT’s.

Cruising at 25 or so 53×13 maybe, sprinting 53×11 (it’s the only way to hit 40 mph) climbing depends on the climb but coulbe be 39×25 or so on the steepest.

  1. Most TDF riders will use a traditional 2 up 5 down ten speed gearing system in order to save on weight. Riders will usually use particularly resistant gearing for flat sections to maximise efficiency and will use a ‘stock’ chain. For climbing and other more technical sections, riders tend to use a long armed crankset, reinforced (often kevlar) chain and something much closer to a normal gear range.
