If the bikes are 7.7 kg (17 lb), throwing a sponsor under the bus isn't the way to get them lighter.
Really though, if he is claiming it to be Look bikes that are too heavy, we need to know the frame weight to compare to other pro frame weights.
EDIT: Look claims a small frame: 890g, 1315g frame+fork, 7kg (15.5 lb) asphalt ready bike on their website.
EDIT 2: Tadej's Colnogo weighs 798g, 1173 frame+fork, 7.25kg (16 lb) complete bike (as reviewed by road.cc with Dura Ace wheels not the Envie wheels that UAE uses...).
