The ENVE M685 Fat Bike Rim part of the M6 Series trail rated mountain bike component group.

With its 85mm internal width this full carbon mountain bike rim available in both 26” and 27.5” diameters is equally at home on the snow, sand, rock, and dirt. 

The M685 has been designed for those who ride and race their fat-bikes year round and need additional volume for backcountry expeditions or simply don’t want a “Snow-Only” carbon fat bike wheelset. 

As with all M Series wheels, ENVE evaluated rim widths and weights to best optimize the preferred tire size choices and ride quality of fat-bikes.

The M685, with a rim weight of 600g and an inner rim width of 85mm, achieves a balance of traction, weight, and mountain bike durability for 3.8-4.5” tires that are best in class.

Utilizing the patented Wide Hookless Bead technology, the tubeless-compatible M685 also protects your tubeless tires from pinch flats.

Additionally, unique shaping for both 26” and 27.5” diameters helps shed snow and sand to keep unnecessary weight off your fat-bike. Lighten your fat-bike for racing, or cover more trail than ever before with confidence and without limitation.
