Team time trial shapes up as Discovery vs CSC show-down

Today's team time trial will be a 67.5km test of discipline, endurance and determination that's likely to at least partially affect the outcome of the race. The team TT won't have as great an effect as it might, as Tour rules limit the amount a team can lose to three minutes, preventing a team that's weak in this discipline from getting knocked right out of the running this early in the Tour. Nevertheless, any team with serious ambitions for the general classification has to ride well today.
