Don't let the name fool you. This rotor isn't buoyant. Without getting to technical, floating refers to the way the aluminum carrier on this 2 piece rotor connects to the stainless steel disc. This technology is commonly used on motorcycles and is one of the best ways a manufacturer can design a rotor that will resist warping. There are lots of manufacturers making 2 piece rotors in the bike industry but Hope is the only one with a true floating disc. That's just one reason why you always want to have Hope... rotors on your bike.
Price Point carries a large selection of disc brakes systems that work great with Hope Floating Disc Brake Rotors.
I have only praise for this rotor. For use on a bike downhill, excellent.
Heard a lot of good things about this rotor. Upgraded my front rotor from a 160 to a 203mm. What a difference in stopping! Made my cheap brakes fell like new again :)
