1. A rotatable handgrip for a bicycle shifter comprising:
- a rotatable member;
a flexible grip disposed over the rotatable member;
wherein a first space is defined between an inner peripheral surface of the grip and an outer peripheral surface of the rotatable member so that the grip bends radially inwardly into the first space to form a first dent in an outer peripheral surface of the grip in response to pressure from a hand part;
wherein a first space-forming recess is formed on the inner peripheral surface of the grip for forming the first space;
wherein a second space is defined between an inner peripheral surface of the grip and an outer peripheral surface of the rotatable member so that the grip bends radially inwardly into the second space to form a second dent in the outer peripheral surface of the grip in response to pressure from the hand part;
wherein a second space-forming recess is formed on the inner peripheral surface of the grip for forming the second space;
wherein the rotatable member includes a grip engaging member projecting radially outwardly from the outer peripheral surface;
wherein the grip includes a rotatable member engaging recess;
wherein the grip engaging member is disposed in the rotatable member engaging recess;
wherein the grip engaging member is disposed circumferentially between the first space-forming recess and the second space-forming recess;
wherein the first space-forming recess is formed by a first grip sidewall facing a second grip sidewall in a circumferential direction; and
wherein the first grip sidewall and the second grip sidewall are disposed clockwise of a first sidewall of the grip engaging member.

Abstract
A rotatable handgrip for a twist-grip shift control device includes a rotatable member and a flexible grip disposed over the rotatable member. One or more spaces are defined between an inner peripheral surface of the grip and an outer peripheral surface of the rotatable member so that the grip bends radially inwardly in response to pressure from a hand part (palm, finger, thumb, etc.) so as to generally conform to the hand part. The space may be formed by a recess formed on the inner peripheral surface of the grip, on the outer peripheral surface of the rotatable member, a combination of recesses on the grip and the rotatable member, or through some other structure.
