700c, 27-Inch & 650c

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 a 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. - 300g rim design optimized for tubeless tires and disc brakes - RiACT rim shape and carbon lay-up absorbs vibrations to give you the best ride possible - 21.6mm internal rim width for more stability and control with all tires - Tubeless ready with rim tape and valves installed - Patented BST tubeless rim inflates easier and offers a more secure tire fit - Optimized for lower pressure 25-40mm disc road, gravel, and cyclocross tires - Includes 12mm end caps
