You gotta get up to get down. The GMD-27 is the perfect all-around trail weapon. With XC bones and a trail riding heart, it is a rolling contradiction between super light and super strong, evolved to inspire confidence in all situations. This wheel system combines all the attributes of our superlight race-oriented GMX-25 wheel with the burly nature of our GME-30 enduro. With the same 3mm thick beads of our enduro rim and a slightly shallower rim profile and adjusted rim layup, this wheel can compete on the climbs and rip the descents without compromise.

Utilizing our top-tier manufacturing process and advanced resin mixture for a rim that comes out of the mold in a glossy finished state, combined with our G1 spoke and hub system that keeps everything laced light and tight. Dial your ride.

    I’ve been running the GMD-27s for 50+ mile back country mountain bike races, and I must say: these wheels are the perfect weapon for the kind of riding that I do! Not only are they super light and nimble on the climbs, but the burlier nature of the wheel allows me to rip down some serious gnar with full confidence!
