Abstract: The present disclosure provides a bicycle hub that provides improved drive line efficiency and bike-to-rider torque feedback. The drive line efficiencies are due to lower rolling resistance resulting from a novel bearing and sprag clutch configuration, a lightweight design, and immediate torque transfer from the cassette drive to the hub body. The bike-to-rider feedback has been improved as the torque transfer is smooth, predictable, and immediate.

Abstract: A sprag clutch based freehub system that has an easily swappable free hub portion is provided. The freehub system uses a cassette driver adapter shaft (also referred herein as “driver”) that is positioned within the hub. The cassette driver adapter shaft (driver) and freehub body have a separable interface. This allows for easy interchanging of freehub bodies by the user while not risking contamination or damage to the hub.

Abstract: Forward movement of a bicycle results when force is transfer from the chain or belt to a sprocket on a cassette. The cassette is splined to the cassette driver and causes the wheel of the bike to rotate when torque is applied from the cassette to the cassette driver. The cassette driver is typically made of a strong hard material such as steel to withstand the forces in parted thereon by the cassette. The present disclosure provide a hub configuration and method that enables the cassette driver to be made with construction of a lighter weight material such as aluminum yet still withstand the toque applied thereto.

Abstract: The present disclosure provides an improved rotor of a centrifugal compressor. The rotor includes a blade arrangement and geometry that increase the overall efficiency of the rotor. In particular, blades within the rotor are curved and inclined in a manner that improves the overall efficiency of the rotor. The present disclosure also provides a method of manufacturing the improved rotor.
