Stan's No Tubes Grail CB7 Pro Wheels

The Grail CB7 Pro is one of the lightest road wheelsets ever made, thanks in large part to its purpose-built 300g carbon rim. Designed to take full advantage of disc brakes and tubeless tires, the incredibly short sidewalls of the Grail CB7 put material only where it’s necessary, lowering weight and enhancing ride quality. The result is outstanding acceleration and a serious advantage on climbs.
