Introducing ONEAER RCS

ONEAER’s newly developed RCS hub boasts an ultra-responsive and smooth rotation efficiency. Its
rapid clutch system uses a six-pawl mechanism, with three pawls engaging while the other three
are in a semi-clutch state. The whole mechanism are engaging every 3 degrees, resulting in 120
engagement points per revolution.

The approach of spoke combination deploy both J-bend and straight pulls, positioning the
straight pull side spokes further towards the center of the wheel. This design ensures more even
angles and tensions on both side spokes, further enhancing performance and durability.

Cassette body tool-free releasing mechanism, allowing a more convenient and easier regular
maintenance job, such as cleaning and greasing.
