It still doesn't make sense. He is trolling us for sure.He had enough gap, that a heavier bike wouldn't be a problem.
Yes, the V5RS is a much better choice for the cobbles, but I still don't understand why he didn't change to the Y1RS for the Ardennes and for the Dauphiné.... if it's a better bike...
This will all become clear after the Tour. If he likes the bike, he will continue to use it in every situation.
For example he lost AGR on rolling terrain, the aero bike would make much more sense and he still rode the V5Rs
