The G23 is the definition of a true gravel rim. At 330 grams, ENVE's lightest 700c tubeless rim accelerates quickly and ascends with ease. Armed against pinch flats with the patent pending Wide Hookless Bead, the G23 is tough and relentless on road, path or trail. The G23 has a generous 23mm internal width, specifically conceived to meet the performance and ride quality demands of serious mixed surface cyclists.
