Stan's NoTubes Grail CB7 28 Inch Carbon Rim

The Grail CB7 rim combines an incredibly light weight with the stability, control and reliability of the most trusted tubeless system. Today's road and gravel tires have evolved. 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 built specifically around this tire breed. Designed for disc brakes and tubeless tires, the Grail CB7's patented low-profile rim increases strength while reducing weight. The rim shape and carbon lay-up of the Grail CB7 allow for outstanding lateral stiffness while offering a soft riding feel. The BST tubeless rim design can take a maximum tire pressure of 85psi (5.9 bar), offering incredible performance for 28-40mm road and gravel tires. The WideRight internal width and impact absorbing RiACT design makes sure speed and reliability are matched by stability and control. The width of the Grail CB7 rim creates a more stable base for your tires, improving both speed and cornering stability. The Grail CB7 rim is constructed using Stan's radial impact-absorbing carbon technology (RiACT) that combines a more compliant lower-profile rim shape with a special carbon lay-up process to absorb vibrations and distribute impacts. For gravel and cyclocross racers, this rim shape also allows for lower tire pressure without the fear of pinch flatting a tire or damaging a rim. Combined with the reliability of a self-sealing tubeless tire, the Grail CB7 provides the stability and control for intuitive handling both on the road and off. Features: optimized for lower pressure tubeless tires and disc brakes RiACT technology absorbs vibrations 21.6mm internal width for more stability and control Technologies: RiACT rims a three times stiffer than Stans regular aluminum rims and absorb radial impacts to withstand bigger hits and roll faster. The WideRight profile increases tire volume without negatively affecting tread shape or sidewall height. Bead Socket Technology (BST) rims are designed to match the shape of your tire's bead to create a safer and more secure air tight interface.
