The Grail CB7 rim combines an incredibly light 300g weight with the stability, control, and reliability of the most trusted tubeless system. Today’s road and gravel tires have evolved. Yesterday’s slow-rolling 23mm tires and energy-robbing extreme air pressures have been replaced with wider, faster, and more comfortable tire designs. The Grail CB7 is the first rim built specifically around this new breed of tire.
