Cav might have an image rights deal with Nike but that will be for images of him wearing Nike clothing (either on or off the bike). That can remain in place if he moved to Adidas-sponsored Sky, he just wouldn't make much money from it any more as who would want to pay to use photos of him in old kit.
It's complicated apparently, as it says here.
Should we make anything of Danny Pate rocking up to Team Sky from HTC this morning?
That's what I thought when I read it this morning.I guess he could form part of a lead-out train too.
Cav hasn't said anything to the press really, so it is hardly fair to blame him for any of the media speculation.
