From our much copied wider rim design to our ground-breaking Bead Socket Technology rim profile we've made a habit of thinking outside the box-section when it comes to rim design. Our new Grail continues the NoTubes tradition of function-first innovation. Countless hours spent working with our professional road racers and cyclocross team led us to create what just might be the ultimate disc-specific rim for road 'cross and gravel. At just over 24mm wide and featuring our deepest profile (24.5mm) the Grail is the most aerodynamic rim we've ever made. Though it rivals much deeper designs in the wind tunnel we designed the Grail to be much more than just fast in a straight line. Our variable wall thickness spoke bed maximizes durability and ensures consistent spoke tension while keeping weight low. Its internal rim channel and true BST sidewalls combine to lend additional strength and create a tire profile that's simply faster. Put to the test in some of the harshest racing conditions the Grail has proven it has what it takes to accelerate quicker and roll faster than the competition. The Grail redefines tubeless road and cyclocross performance.

Road tubeless tyres are a very snug fit so it is vital to always mount the valve area last. The valve sticks out of the channel of the rim and interferes with the tire bead in that area - in effect making the tire have to stretch further than it would if the valve were not there. To avoid this begin mounting the tire opposite the valve then work both sides around toward the valve area and mount the valve area last. The Grail rim is a disc specific model so the sidewall does not have the extra bulk of a machined braking track. Using tyre levers to mount a very tight tyre could cause damage to the rim and will not be covered by warranty. It does require a Road Tubeless Tire for high pressure use; over 40-45psi. For tubeless Cyclocross use we do not recommend going over 40psi which is in line with our mountain bike line of rims.
