1. Keeping form this long is kinda special. It happened before (Wiggins), but it's odd to think it will last.
2. Airstream called Wiggins and Froome undoubtedly
the best two GT riders based on this and last season. I have shown rather decisively that Wiggins neither has the form nor palmares to warrant that claim. Last season is a similar problem. The only time AC met Froome in a GT he crushed him. He did not say "Froome is at this moment in time the worlds best Stage rider", he specifically added GT's and last season. Does not compute
We will see. It's not yet July. Wiggins clearly isn't at peak yet and if he manages to get peak form in July he won't be a pushover. It also depends on how the competition is stacking up. You assume Froome will do the attacking, but if Ryder, Andy and/or Alberto are at their peak form there's a decent chance Sky will have to ride defensive to take them out on the TT's (Where Froome beats all three). If that happens Wiggins is in good position again.
For sure, I think Froome will be the one to beat, but we have seen in the past that it can be a complete surprise how it turns out.
