Stan's No Tubes Grail CB7 Rear Wheel - 700 12 x 142mm Center-Lock XDR Gray. 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. The Grail CB7 proves that smoother is faster by combining lateral stiffness with the soft riding feel. That special ride is about more than just comfort. Decreased resistance from road impacts and less shoulder and arm fatigue means more power to the pedals and a faster rolling wheelset.
