These Enve M-Series mountain wheels come built with Black Boost 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.
