ABSTRACT:
A shifting device includes a generally cylindrical main body part having a first end portion and a second end portion. An attachment part is fixed to the first end portion of the main body part, and the main body part includes an opening for receiving the cable therethrough. The attachment part may extend at a selected angle from the main body part for fixing the main body part to the free end of the handlebar. A winding member is disposed within the main body part, wherein the winding member has a winding surface for winding the shifter cable. A first end region of a connecting member is fixed to the winding member, and a partition member is disposed about the connecting member for positioning the connecting member within the main body part. An operating member is disposed at the second end portion of the main body part and is fixed to a second end region of the connecting member so that rotation of the operating member causes rotation of the winding member. A spring is provided for biasing the operating member in a particular direction. A first end of the spring is fixed to the partition member and a second end of the spring is fixed to the operating member.
