ENVE M6 27. 5 CL Wheel Trail-tuned The new ENVE M6 Wheel is designed for versatility, from the daily trail rides to the backcountry epics, with more durability, comfort, and traction than any other wheel in its class. Like the other M-series wheelsets, the M6 features a unique front and rear rim design.

At the heart of the wheels is the ENVE INNERDRIVE hub system, boasting increased freehub engagement with drive ratchet upgrade options, and ENVE's Perfect Preload system for a longer wear life.
