Not sure Froome is bad at descending at all. Nibali is widely regarded as the best descender among the usual GC type rider and he crashed out on Saturday. Just hope everyone gets down alright as you won't want to go onto the road markings in this rain if you can help it. Even trickier in windy conditions on a time trial bike.
I can see it being used today too. Tom Dumoulin is one of the favourites in the blokes race, but he broke a hand in the Tour so is he going to go hard on the descent? Hmm.
...fascinating, risk/reward or safety first. Be interesting how Pooley is doing at the first split.
