As with all ENVE M Series wheels, the M685 was designed considering rim widths and weights to best optimize the preferred tire size choices and ride quality of fatbikes. The M685, with a rim weight of 600g and inner rim width of 85mm, achieves a balance of traction, weight, and mountain bike durability for 3.8-4.5” tires. Utilizing ENVE patented Wide Hookless Bead technology, the tubeless compatible M685 also protects your tubeless tires from pinch flats. Additionally, unique shaping helps shed snow and sand to keep unnecessary weight off your fatbike. Lighten your fatbike for racing, or cover more trail than ever before with confidence and without limitation.
