Abstract
A handlebar gear shifter includes a sleeve rotatably mounted to the handlebar from which a support plate extends. An L-shaped mediate member has an end pivotally connected on the support plate and a first cable has one end thereof engaged with a recess in the sleeve and the other end of the first cable is engaged with the mediate member. A second cable is connected between the mediate member and a derailleur mechanism. A C-shaped member having notches is connected to the handlebar and a spring member is engaged with the sleeve. An index member is biased by the spring member and removably engaged with one of the notches. The mediate member is pivoted by rotating the sleeve which pulls the first cable, and the second cable is pulled together with the mediate member to shift the gear.
