BIG FLATS, N.Y. (BRAIN) — Stan’s NoTubes has announced the new Grail CB7 and Grail MK3 rims and wheelsets.
“Today’s more versatile drop bar bikes demand a new kind of tubeless rim, one that’s as capable of crushing 200 miles of gravel as it is scaling above category climbs. Optimized for tubeless tires and designed for disc brake-only use, the new Grail CB7 and MK3 rims and wheelsets combine the best characteristics of classic ultralight road wheels with new levels of reliability, control and comfort,” the company said.
Grail CB7 and MK3 rims and wheelsets will be available this month.
The Grail CB7 rim is designed for 25-40 millimeter tires and a maximum pressure of 85 psi/5.9 bar (with 25 mm tire). Developed specifically for tubeless tires and disc brakes, the Grail CB7 uses Stan’s patented low-profile rim shape. The rims weigh 300 grams.
The Grail CB7’s has a 21.6mm internal rim width and shaping that Stan’s said keeps larger tires from folding over on the rim, even under the lower pressures and hard cornering of cyclocross and gravel races. The company said the rim shape also prevents tire pinch flats and makes tubeless setup faster, easier and more reliable.
