Abstract
The subject invention relates to a type of hub structural improvement, comprising mainly the clutch mechanism that is composed of a clutch and the ratchet teeth of the bearing housing inside the hub; so that the whole unit can independently perform a single-direction brake function; without additional components as in conventional structures; with its high compatibility of components, only the chain wheel support has to be replaced in case of additional function of multi-step speed changes; without replacing many components as in conventional structures, which would result in higher assembling costs; under the trend of ever-changing bicycle specifications, it will reduce the change of measurements of relevant components, thus reducing the production costs.
