I've never watched this before but am watching the 2013 coverage on eurosport at the moment to get in the mood for sunday!
Anyway i've got a couple of questions…
the cobbles are rated 1-5, is a 1 star section really rough / bumpy and 5 stars a better condition surface, or is it the other way round?
I've also noticed on some of the cobble bits guys at the side holding wheels up in the air, is this just because the cobble bits are too narrow for the support cars to follow closely, so do they have support teams on each cobbled bit?
Do the bikes still have any form of suspension? I seem to remember reading years ago about some teams using suspension forks.
