The G27 is the G23 little big brother. Smaller in diameter and lighter in weight, the G27 is designed for disc brakes and 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.
