Today's rider demand a new breed of wheel, one as fast on paved above category climbs as it is on 200 miles of gravel. Designed from the ground up to optimize lower pressure tubeless tires and disc brakes, the Grail CB7 combines the best characteristics of an ultralight road wheel with new levels of stability, control, comfort and durability.
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 Stan's first rim built specifically around this new breed of tire. The BST tubeless rim design of the Grail CB7 can stand a maximum tire pressure of 85psi (5.9 bar), offering incredible performance for 28-40mm road and gravel tires. Above all else, the Grail CB7 proves that smoother is faster by combining lateral stiffness with the softest riding feel. Decreased resistance from road impacts and less shoulder and arm fatigue means more power to the pedals and a faster rolling wheel.
The "WideRight" 21.6mm internal width and impact-absorbing RiACT design make sure all that speed is matched by stability and control. 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 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.
Features:
- optimized for lower pressure tubeless tires and disc brakes
- RiACT technology absorbs vibrations
- 21.6mm internal width for more stability and control
- elaborate CNC machined hub shell
- Tubeless ready with rim tape and valves installed
- lightweight Neo Ultimate hub with stainless steel bearings
- Sapim spokes with Secure Lock nipples
- Low-drag main seal prevents contamination and reduces resistance
- Laser-etched SealLock end caps lock into place and roll smoother
Technologies:
RiACT
Rims with this technology are three times stiffer than Stans regular aluminum rims and absorb radial impacts to withstand bigger hits and roll faster.
WideRight
This 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.
