These Enve G-Series gravel wheels come built with Black Industry 9 Hydra Centerlock hubs
THE NEW PHASE OF INDUSTRY NINE is the culmination of innumerable miles on the bike and hours in the shop. An evolution from previous drive systems, our new HYDRA drive is a project over two and a half years in the making.
Hydra rewrites the rules with a monstrous leap to 690 points of engagement, or .52°between each engagement. The new Hydra drive system raises the bar on hub technology using an independently-phased six pawl, 115 tooth drivering.The innovative new design utilizes a continually phased system, creating a procession of engagement points between pawl and drivering. The design utilizes the inherent flex of the axle to accomplish positive second, third or fourth pawl contact. Hydra also tempers uncontrolled axle and bearing movements conventional designs can't mechanically limit, thus improving bearing life and decreasing resistance. Hydra offers consistent, reliable engagement without overloaded bearings, axles or hub shells.
The G23 is the definition of a true gravel wheelset. 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 is a 700c tubeless carbon clincher wheelset, with a generous 23mm internal width, specifically conceived to meet the performance and ride quality demands of serious mixed surface cyclists.
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.
