Abstract
Nubbed grips for hand-rotatable bicycle gear shifters have longitudinally elongated groups of nubs (50, 96, 142) that are angularly spaced apart by valley regions (44, 98, 156). Preferably, the elastomeric nubs are formed both on a cylindrical portion and an adjacent flanged portion of the grip. In an alternative embodiment, shark tooth nubs (142) offer leading faces (158) against which a hand of a rider may abut in either rotational direction for maximum torque transmission.
