What It Is The G27 is the G23's little big brother. Smaller in diameter and lighter in weight, the G27 is designed for the higher-volume tires demanded by many riders on rougher and looser terrain. At 320 grams, our lightest tubeless rim is 27mm wide and designed for tires marked 27.5 or 650B. Armed against pinch flats with the patent-pending Wide Hookless Bead, the G27 is at home off-road and capable on tamer stretches of singletrack. Who It's For Those seeking the challenge of drop-bar riding over more technical terrain that is typically frequented by mountain bikes will benefit from the additional air volume, durability, and anti-flat performance benefits provided by the G27. If your path leads you to rough roads, single tracks, and multi-day bikepacking adventures, the G27 may be for you. Why We Made It There is a place between road and mountain that is open to discovery. Beyond the range of your trail bike or the capabilities of your road bike. Terrain littered with contradicting challenges and demanding requirements are at odds with the bikes and products available today. We built the new G27 to thrive in this new environment because insights gained through building the world's best road and mountain bike rims told us that the perfect combination did not exist in our stable, or in our opinion, anywhere at all. The higher volume and lower pressures would demand MTB toughness and flat resistance, while big days and long miles would require the light weight and efficiency of a road machine. Above all, the combination of rough and rigid would require a wheel with the ride quality to make those long miles enjoyable and multi-day treks possible.

What It Is The definitive mountain wheel. The M6 Series defines the modern and varied interpretation of the mountain bike. Loaded with traction and acceleration on the climb, it's also backed with precision and control while absorbing vibrations and impacts on the descent. The M6 Series is designed in two diameters and three widths to ensure your sophisticated preference for tire size and pressure is met with an uncompromising tire-to-rim interface. Who It's For The mountain biker who wonders what is possible, the skeptic afraid of "plastic" wheels, the weight weenie, the Clydesdale, the high-mileage guy, the weekend warrior. It would be easier to describe who it is not for… Why We Made It ENVE showed the world that a mountain bike wheel could be carbon — we're still immensely proud of that achievement. A mountain bike wheel, however, can be so much more. The M6 Series is not about technical challenges, and we refuse to chase specifications in order to be the widest, tallest, or stiffest. For the M6 Series of wheels, the question was not about carbon, rather, "What is the potential of a mountain bike wheel?" Each M6 Series wheel model is designed for the broad range of tire widths, hub configurations, and sizes so that you, the modern trail rider, can choose between them.

- Lighter, wider, stronger and more flat resistant - Ride Tuned – Smoother ride improves tracking, control, and reduces fatigue - Wide hookless bead dissipates impact energy and prevents pinch flats. - 30% increase in impact toughness, 60% more flat resistant - Optimized for 2.3-2.5" tires
