Question: what gearing do tdf riders use?
Answer: j/k lol kthxbye! Standard flat stage gearing for the pro's is a 53/39 with an 11x23 in the rear. For climbing stages in the TDF they likely will stay with a standard up front and will use anything from an 11x25 to 11x32 depending on the rider...the climbs are not steep enough to warrant droping to a compact in the TDF.
