Do they do anything? Call me ignorant, but I don't think they deserve their spot in the Tour. They're supposedly a Basque pro team, composed mostly of climbers, but I don't recall any climbing stages or jerseys being won by them lately.
I've also never seen one of their riders do anything but become a rolling chicane in the group sprint, and has a TV camera ever even followed one during a TT?
IMO, there are teams more deserving of their spot in the Tour.
