5-Year Limited Warranty and Lifetime Incident Protection
What is it?
A M6 Series trail rated 85mm internal width full carbon mountain bike rim available in both 26” and 27.5” diameters that is equally at home on the snow, sand, rock, and dirt.
Who's it for?
The M685 is for those who ride and race their fat-bikes year round, need additional volume for backcountry expeditions, or simply don’t want “Snow-Only” carbon fat bike wheels.
Why we made it?
As with all ENVE M Series wheels, we 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 inner rim width of 85mm, achieves a balance of traction, weight, and mountain bike durability for 3.8-4.5” tires that’s 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.
SNOWSHED SIDEWALL DESIGN
One goal of lightweight carbon rims is to reduce rotating mass. With fat bikes, we found that some rim designs while respectably light, tend to collect snow that can add literal pounds of rotational weight to each wheel in the form of snow or mud, so we solved that problem. The M685 features a 45mm deep cross-section and steeply angled sidewalls that are specifically designed to shed snow and eliminate the possibility for debris traps.
ASYMMETRIC MOLDED SPOKE HOLE DESIGN
The M685 features an ENVE first asymmetric molded spoke hole design. This design offsets each spoke hole so that optimal spoke alignment and angle can be achieved. Each spoke hole is locally reinforced to further assist in saving unnecessary rim weight. This design also maintains the spokes as far from the snow as possible which further aids in preventing build up on the rim.
At ENVE we believe that tubeless is the only way a modern wheel and tire system should be set up. The benefits of riding tubeless tires are many, but can be highlighted by improved rolling resistance, ability to run lower tire pressures leading to greater traction when climbing, braking, or cornering, and a reduced propensity for pinch-flatting. Each ENVE M Series wheel is molded to exacting bead seat diameters to ensure easy and reliable tubeless compatibility.
WIDE HOOKLESS BEAD
Taking the lessons we’ve learned from the M Series wheels, the M685 adopts similar Pinch Flat Resistance through our patented Wide Hookless Bead Technology. Ride in confidence at the pressures you prefer, no matter the terrain.
ENVE’s wide hookless bead is the result of 2 years of carbon mountain bike rim development to address pinch flats. The result is a rim shape that features a wider leading edge of the hookless bead. This broad surface creates a more forgiving platform on which the tire can bottom out, and proves extremely effective in reducing the likelihood of “pinch” or “snake-bite” style flat.
In addition to greatly improving tire performance and reliability, the wide hookless bead design beefs up the leading edge of the rim and allows for greater impact resistance.
