DESCRIPTION

The Grail CB7 wheelset combines an ultralight 300g carbon rim engineered to absorb impacts with durable and smooth-rolling M-pulse hub to create the best tubeless wheelset for gravel and adventure road riding.

When it comes to tubeless technology, Stan’s wrote the book. Five patents and countless hours testing and refining have led to the 300g Grail CB7 carbon rim’s easy inflation and reliable airtight seal. The Grail CB7 has a maximum tire pressure of 85psi (5.9 bar), making it ideal for 25-40mm tubeless road and gravel tires. More traction, more comfort, and the ability to seal punctures as you ride make the Grail CB7 the best choice for riding and racing on gravel.

Built using our radial impact-absorbing carbon technology (RiACT), the Grail CB7’s shape and material placement work together to dampen vibrations and distribute impacts for a more comfortable ride that rolls faster, too. Whether saving energy for a late race attack, or just the extra loop to the best coffee shop, the Grail CB7 lets you ride further, faster, and flat-free.

One of the lightest and smoothest gravel rims deserves a special hub, and the Grail CB7 rolls on M-pulse hubs. The magnetic pawls of the M-pulse hubs are at their strongest when engaged, but, unlike traditional pawl designs, offer very little friction and resistance when not engaged. The result is a smoother, friction-free feeling of pure forward momentum. To reduce drag even more, M-pulse hubs offer preload adjustment, allowing the bearings to spin as smooth as possible. M-pulse freehubs are designed and manufactured in Bend, Oregon by Project321. They’re available for Shimano Micro Spline and HG as well as SRAM XDR cassettes, and are offered in all common axle sizes.

From the highest levels of gravel racing and cyclocross, to road rides that leave the road behind, the Grail CB7 is the lightest, smoothest, and fastest wheelset you can own.


WHAT'S INCLUDED:

Grail CB7 wheels include pre-installed tape for tubeless use and presta valves.

Three times stiffer than our aluminum rims laterally, but absorbs radial impacts to withstand bigger hits and roll faster.

Our WideRight profile increases tire volume without negatively affecting tread shape or sidewall height.

M-pulse hubs offer near instantaneous engagement, a more secure and positive lock when engaged, and very low drag for less rolling resistance.
