Stans NoTubes Grail MK3 Rear Wheel

Stan's NoTubes wants to equip you with wheels that ensure you can ride the discipline of choice without limits. Or perhaps you don't have to narrowly define your goals. For pavement, gravel, cyclocross, and even singletrack, the Grail MK3 is ready to carry you to outperform the competition on every surface. Stan’s tubeless technology offers less rolling resistance, more control, and the ability to seal most punctures almost instantly while you keep riding. The Grail’s versatile, 440 gram BST-R rim design makes it compatible with tubeless road tires, low-pressure tubeless converted tires, and conventional tires and tubes, offering maximum flexibility in a single 1675 gram wheelset. Upgrade your bike to the leading tubeless rim design, and find out what you’ve been missing.

The Grail MK3's internal width and patented Bead Socket Technology rim design are optimized for 25-40mm tires according to NoTube's WideRight framework. We offer the Grail MK3 in individual front and rear wheels. Buy both to own one of the most versatile rim designs offered. The reality is that wider is faster, more stable, and more efficient in mix surface conditions, and the rim shape of the Grail MK3 Rear Wheel lets you get the most speed from your tires. The rim itself features a 20.3mm internal width, with a 24mm external measurement and a 24.5mm profile height for a well balanced, stable, and strong hoop. All the advantages the Grail MK3 offers on the road are even more noticeable once the pavement ends. For cyclocross and gravel racing, the optimized tire shape and added stability offer a distinct advantage. The Grail MK3's rim shape is even designed to avoid tire pinch flats, allowing cross and gravel racers to run lower pressures that absorb impacts and improve traction.

Nobody likes flats. Combined with Stan’s sealant, tubeless tires have the ability to seal punctures while you keep riding, adding a new level of security and convenience. Constructed from lighter, stronger 6069 series aluminum, the Grail MK3 rim is also strong enough for serious adventure on and off the pavement. As a rear wheel, with triple freehub bearings, co-molded seals, and full CNC machined bodies, the Grail’s NEO Durasync equipped hub utilizes 10-degree engagement via a simultaneous 6-pawl freehub design that delivers power, control, for maximum durability for performance and high mileage in all conditions. Laced with traditional and readily available j-bend Sapim spokes, the Grail MK3 is built to be the only rear wheel you need for anywhere the ride takes you.

Fast, tough, and featuring the most trusted tubeless technology in the world, the Grail MK3 is ready to improve every ride, both on and off the pavement. To find out just what you and your bike are truly capable of with the Grail MK3, starting here with the rear wheel, set up with a 12/142mm thru-axle NEO hub, 28 spokes, and prepped for tubeless use with tape and valve installed.
