Abstract
The disclosure relates to a hub assembly for a driven wheel of a bicycle, comprising a hub shell for connection to a rim of the driven wheel, and an exchangeable drive assembly for being exchangeably couplable to the hub shell. The exchangeable drive assembly comprises an axle; a substantially cylindrical driver body rotatable about the axle and configured for carrying a cassette of sprockets; and an inner hub body rotatable axially adjacent the driver body about the axle and comprising a splined first coupling interface configured for providing a direct-drive coupling between the inner hub body and the hub shell and a second coupling interface configured for providing a direct-drive coupling between the inner hub body and the driver body.

A kit comprising a hub shell for connection to a driven wheel of a bicycle, an exchangeable first drive assembly and an exchangeable second drive assembly each for being exchangeably couplable to the hub shell,
- the exchangeable first drive assembly comprising:
- a first axle;
- a substantially cylindrical driver body rotatable about the axle and configured for carrying a cassette of sprockets of a first type;
- a first inner hub body rotatable axially adjacent the driver body about the first axle and comprising a splined first coupling interface configured for providing a direct-drive coupling between the inner hub body and the hub shell, and a second coupling interface configured for providing a direct-drive coupling between the inner hub body and the driver body;
- the second drive assembly comprising:
- a second axle;
- a substantially conical driver body rotatably about the axle and configured for carrying a cassette of sprockets of a second type;
- an second inner hub body rotatable axially adjacent the driver body about the axle and comprising the splined first coupling interface configured for providing the direct-drive coupling between the inner hub body and the hub shell;
- a switchable transmission operative between the driver body and the inner hub body.
