Abstract
A bicycle gear shifting system includes a gear shifting derailleur, a rotatable shift member to be rotatably carried by handlebars of the bicycle and connected to the gear shifting derailleur, and a hand attachment to be carried by a hand of a rider. The rotatable shift member and the hand attachment may each have respective mating surfaces for positively engaging one another to facilitate gear shifting by the rider and are readily releasable to permit the rider to change hand positions. More particularly, the mating surfaces may include pairs of corresponding recesses and projections. The pairs of corresponding recesses and projections may also be tapered. Furthermore, the mating surfaces may engage in superposed relation upon radial squeezing of the hand of the rider. According to another embodiment, the mating surfaces may engage in side-by-side relation upon lateral positioning of the hand of the rider.
