Be interested to see which riders opt for Giro rather than Tour. The Giro is having its 100th edition which should hopefully give it some additional pull vis-a-vis the Tour and Giro. There's more time trialing so Dumoulin and Jungels are obvious calls and definitely see this as the best opportunity for the second string challengers such as Chaves and Kruijswijk but be interested to see whether Contador and Nibali give it a go as I personally don't see them winning the Tour unless a major incident happens and takes out Froome and Quintana. This is particularly the case as they're both joining new teams which may lead to some teething problems (although may on the other hand get Vino and Tinkov off their backs).
