I realize it is carbon, but that isn't even close to sinking. As you might have seen, none of the bikes I asked about are anywhere close to 15kg, so I think it might be close. What is the volume of a 700 X 25c tire?
After the rims and frame filled up (this would take a while), it might have a tougher time floating. He might have specially prepared the frame to be water tight. Rims would be tougher (rubber washers on the nipples?).
I think once you get up to 2" tires on a 25-lb bike you have a good chance of floating the bike even if the frame fills up with water.
This bike weighs close to 50lbs and floats quite well with its 4" tires.
