    ZTR Grail Disc Rim.  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.
