Just wondering how the mechanics get a rider properly positioned (saddle height, etc.) after giving him a new bike. I have seen a couple of those switches so far, but no messing around with hex keys, etc.
I guess that the team cars carry spare bikes with the right specifications for the team leaders. But there's hardly room for 'carbon copies' for all the riders, is there?
One of the Euskaltel riders was seen switching to yet another bike (or perhaps back to his 'original' one) after he had been given a replacement bike. That would confirm that the spares do not always match riders' sizes, I think.
