The Chronos Rear Disc Hub is engineered for the long haul - whether that’s a self-supported tour across state lines or a rain-soaked daily commute. By utilizing a floating ratchet system, we’ve moved away from traditional pawls to provide excellent engagement that handles high torque loads with ease.

We designed these hubs with oversized flanges to house large, premium sealed cartridge bearings, ensuring a smooth spin regardless of the mileage. Maintenance is entirely tool-free; the endcaps and freehub body can be removed by hand, making roadside driveside spoke replacements a minor detour rather than a trip-ender.
