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.

RCS + CeramicSpeed

The RCS CS equipped with Six 6 CeramicSpeed bearing in front & rear.

◆ Extremely low friction

◆ Improved power transfer

◆ 3-5 times longer lifetime compared to industry standards

All CeramicSpeed Bearings are hand-built in Denmark. Super smooth CeramicSpeed grade 3 Silicon Nitride balls are matched (within microns) with hardened steel raceways that feature an ultra-smooth polished groove.

During the building process, we check each bearing four times by hand to ensure that all parts are matched perfectly. CeramicSpeed Balls are 400% smoother, 128% harder and 58% lighter than standard steel bearings normally used in the bicycle industry. When comparing the CeramicSpeed Balls with other ceramic balls in the industry, you will find that the CeramicSpeed Balls are 15% harder, take 99% higher loads and are 100% smoother.
