From their replicated wider rim design, to their standard-setting Bead Socket Technology rim profile, Stan's No Tubes' has thought outside the box-section for their Grail rim design. The Grail Comp carries out the No Tubes tradition of innovating with a "function-first" mindset. After relentless hours of working and testing with Stan's sponsored road racers and cyclocross team, the initial blueprint for the Grail Comp wheels was drafted up. The result is what may be the most unrestricted, disc-specific rim for the pavement, cross-course, and gravel. Measuring in at over 24mm wide and 24.5mm deep, the Grail Comp carries the title of "Stan's deepest profile", making it the most aerodynamic rim they've produced.
Knowing that aerodynamic properties aren't everything when it comes to burning around tricky cross courses, Stan's No Tubes designed the Grail with a variable wall thickness spoke bed that maximizes durability and provides consistent spoke tension while keeping weight at the lower end of the scale. Its internal rim channel and true BST sidewalls coalesce to lend supplementary strength and create a tire profile that's just plain faster. Put to the test in some of the cruelest racing settings, the Grail has proven it has what it takes to accelerate quicker and roll faster than the competition, changing the way you think when it comes to tubeless road and cyclocross performance.
The resilient Grail rims are laced to Stan's new Neo hub system which features larger bearings and a stronger, stiffer, shoulderless axle that creates a stiff and durable core that is light enough to tackle quadbusting climbs, nimble enough to pick through dirt sections, and strong enough to take the occasional big hits. Additionally, the 4 precision pawls simultaneously engage a 36-tooth ratchet ring, delivering an insanely fast 10-degree engagement. The Neo hubs also offer a 100% CNC machined hub shell and tool-free disassembly, while the new SealLock end caps stay put and make wheel installation a painless affair.
Bead Socket Technology (BST-R) is optimized for narrower rims and features a profile that is designed to create a more secure air tight seal at the bead
Built in the USA on NoTubes Neo hub with Sapim Force spokes and Secure Lock Nipples
Includes: pre-installed tubeless tape, tubeless valves, 12 x 100mm front end caps, front and rear QR end caps and spacer for 10-speed cassettes
