    Abstract: A cushioned grip having a unitary tubular-shaped body portion with an asymmetrical off-center cross-sectional shape.

The asymmetrical cross-sectional shape provides a first portion having a first thickness of cushioning material, a second portion having a second lower thickness of cushioning material and a third portion of further reduced thickness of cushioning material. The third portion of cushioning is provided with a flat surface to provide a positive and solid feel to the fingers while grabbing the grip. The center's curvature defined by the outside of the cross-sectional shape of the grip is displaced from the center of the inside portion which is generally circular and adapted to receive a hard round member such as a bicycle handlebar to be cushioned.
