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 BST tubeless rim design of the Grail CB7 has a maximum tire pressure of 85psi (5.9 bar), offering incredible performance for 28-40mm road and gravel tires. Above all else, the new Grail CB7 proves that smoother is faster by combining lateral stiffness with the softest riding feel of any wheelset. 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.
The Grail CB7 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.
The Grail CB7’s WideRight 21.6mm internal width and impact-absorbing RiACT design make sure all that speed is matched by stability and control. Wider rolls faster, and the shape of the Grail CB7 rim is designed to work with the shape of your tires, creating a wider and more stable base that improves both speed and stability in the corners. Stan’s radial impact-absorbing carbon technology (RiACT) combines a more compliant low-profile rim shape with a special carbon lay-up process to create a rim that better absorbs vibrations and distributes impacts. The Grail’s incredibly short sidewalls and RiACT technology allow for low tire pressures without the fear of pinch flatting a tire or damaging a rim, offering decreased rolling resistance and peace of mind in all conditions, everywhere you ride. The added width and RiACT technology of the Grail CB7 mean stability and control for intuitive handling both on the road and off.
One of the biggest advantages of a tubeless wheel is the ability to seal flats almost instantly while you ride. With five patents on tubeless rim design (and counting), Stan’s NoTubes is the leader in tubeless innovation, and nothing beats the durability, convenience, and performance of our Bead Socket Technology. The Grail CB7 provides the amazing traction and control only a Stan’s tubeless system can offer, along with the ability to seal flats while you ride. Tubeless is the future of performance for road and gravel wheels. With the Grail CB7 wheelset, that future is here.
