No, not weird at all for a domestique. It's pretty weird for a guy who keeps talking up how his form is coming back and whose fans claim he works harder than anyone else. The bar for Froome is GT winner. His history and his contract set that bar. His talk sets that bar. It's probably also fair to say the season is about over and he's not trying to gain form anymore.I'm pretty sure he just rode straight to the finish after he was done working. Nothing weird about that really, so it's a bit of a cheap shot.
He should probably just talk less and ride more.
