Just finished watching the race last night and wow the power that Degenkolb put out on 2 was pretty impressive. However it seems he did suffer pretty much on the ground after the race. The finish on stage 4 was a let down. Seems like the only team that had their train in place and working efficiently was Etixx-Quick-Step.
I liked this quote which sums it up for Giant:
Giant’s road captain, Roy Curvers, said "it was both a disappointment and an education to lose the leader’s jersey."
