Drive Six To explore more terrain, our carbon wheels are constantly being upgraded to allow riders to go faster and farther. DRIVE SIX is available in gravel and MTB versions. The difference between these two versions is the hub. With full carbon spokes, DRIVE SIX wheels provide more direct power transmission. In order to adapt the wheels to more complex road conditions, every detail has been optimized.

One-piece design with 6 carbon spokes increases rigidity and power transfer values. Carbon spokes transmit power more directly than steel spokes, so less force is needed when climbing and accelerating. Silver decals with hand-stacked marbling set the DRIVE SIX wheels apart. RIM TYPE With its hookless full carbon and tubeless ready rim, DRIVE SIX is compatible with 700*28C–700*50C tires. Note that if you are using tubeless tires, first inflate the tire to 90-100 psi, allow the tire edges to expand to the sides of the rim, then reduce the pressure to 50 psi. GRAVEL HUB The hubs of DRIVE SIX is made of 7075 aluminum alloy material. The freehub is designed with a ratchet mechanism and comes as standard with 36 teeth.
