Steuerungseinrichtung für eine Fahrradgangschaltung

摘要

A bicycle shift control device (12) includes a fixed member (22) and a rotatable member (60) rotatably coupled to the fixed member (22) for rotation around a handlebar (14) between at least two shift positions. The fixed member (22) is adapted to be coupled to the handlebar (14) adjacent a hand gripping area A of the handlebar (14). The rotatable member (60) has inner and outer axial ends with a tubular outer actuating surface extending between the inner and outer ends and around a center longitudinal axis X of the hand gripping area A. The actuating surface (82) is configured to define a tubular hand grip with a finger operating projection extending outwardly relative to the tubular hand grip. The actuating surface (82) includes a first portion (84) constructed of a first material and a second portion (86) constructed of a second material more rigid than the first material. The second portion (86) has the finger operating projection (88).
