Abstract
A sensor retainer for a bicycle sprocket assembly includes an annular member for mounting and rotating coaxially with the bicycle sprocket assembly and a sensor element fixed to the annular member. Alternatively, the sensor retainer may include a fixing member for mounting a derailleur or other transmission to a bicycle frame and a sensor element mounted to the fixing member.
Claims41
A sprocket assembly for a bicycle comprising:
- a sprocket mounting sleeve adapted to be rotatably supported relative to an axle;
- a plurality of sprockets coax ally mounted together on the sprocket mounting sleeve for rotation relative to the axle;
- a sensor element mounted to the sprocket mounting sleeve for integral rotation with the plurality of sprockets;
- and
- wherein a laterally innermost side of the sensor element is disposed laterally outwardly from a laterally outermost side of the late ally outermost sprocket.

A sprocket assembly for a bicycle comprising:
- a plurality of sprockets mounted together for rotation around a common axis, wherein the plurality of sprockets includes a firs sprocket and a second sprocket, and wherein the first sprocket includes a shift facilitating structure for facilitating shifting of a chain from the second sprocket to the first sprocket;
- a sensor element coupled for rotation with the plurality of sprockets;
- and
- wherein the sensor element and the first sprocket are structured to be located relative to each other at a predetermined subset of rotational positions less than all of the possible rotational positions of the sensor element relative to the first sprocket, and to prevent the sensor element and the first sprocket to be located at relative rotational positions other than the predetermined subset of rotational positions.
