They'll be doing it in a sub-optimal manner though. The Sky bottles contents are measured out to the ml depending on where the handler is standing on the course and specific micro climate modelling for that location; it's more expensive, but anything other than that is just a waste of time.
Speaking of bottles, I'd like to think that Luke Rowe was the Sky rider who chucked a bidon at the wheel of LaPorte's Confidis team mate who nearly crashed the peloton when he stopped dead in the road yesterday.
