DOUBLE TIME™ ratchet design gives you smooth 6.9-degree engagement-all while keeping everything light and steady. Super-precise SPEEDBALL™ bearings mean lower resistance, faster revolutions and no more time spent readjusting play. From pawl tooth to side cap, we went the extra mile on the X0 Hub-so you have less to worry about on the trail.|Go with what works. X0 Hubs can be customized perfectly to your ride.

Ratcheting up the smarts. This straight-aligned, 4-pawl design turns the 26-tooth ratchet ring into 52 points of contact. The result: smooth 6.9-degree engagement without reducing tooth size or offsetting internal geometry—which means serious long-term durability.
Get unbent. 3D forged and machined for lightweight strength, the flanges are angled towards the rim—allowing the spokes to be fully in-line when tensioned. The result: reduced spoke head breakage and better overall durability.
Switching axles has never been easier. Threadless side caps can be installed and replaced by hand—no tools necessary. SIDE SWAP SYMMETRICAL side caps refuse to take sides. The left side cap is identical to the right one. No need to figure out where each cap is going.
The only adjustment they’ll ever need was made back at the factory. Every part of the ball bearing comes from the exact same supplier—which means that each bearing bore can be precision machined to fit the bearing race exactly. With tolerances this tight, the days of adjusting play after every ride are over. SPEEDBALL CERAMIC option available with ceramic balls for faster, smoother and longer lasting bearings.
XD DRIVER BODY
XD is a cassette driver body design that allows the use of a 10-tooth small cog and provides an improved interface with the cassette.
BOOST is the standard wheel and drivetrain specification that opens the opportunity for improved frame geometry with shorter chain stays, wider and stiffer suspension pivots, wider range of chainring options, as well as more clearance for bigger tires and wider, stiffer wheels.
Torque Caps make the bond between hub and fork dropout stronger, with an increased surface area connecting the two. This creates a stronger, stiffer interface, giving you a more responsive front wheel and more control. So you concentrate on the most important connection, the one between your bike and the trail.
