No need to buy it when it's released. Am sure you will be able to find it only a few months after, laying in one of those small baskets in front of stores with raindrops on the cover, costing a few euro. It's gonna be a sad sight...
I admire Froome, think he's an exciting rider and would applaud him should he win the Vuelta. However if he can ride two grand tours without having a bad day and losing time to some of the other favorites, I would find it difficult to believe he is clean.
