Abstract: A solid handlebar expansion sleeve which expands and shapes any desired portion of handlebars to increase a rider's control by engaging the forearm muscles through accommodating the full use of the length of the phalanxes of the fingers encircling the sleeve. This enables the rider to achieve a solid, full-fisted grasp, relying on the forearm muscles and avoiding wrist fatigue to become an ergonomically healthier grip. The handlebar extension is a split sleeve formed of rigid, molded plastic, with a series of three recessed screws, in an ergonomic, eccentric, oval shape which has a larger-diameter rounded palm receiving portion on top, and, a smaller-diameter rounded phalanx receiving portion extending away from the handlebar along the bottom. The two flat sides between the rounded portions receive the phalanxes of the fingers, contacting the flat sides with the fingers in a V-shape.

Additional finger bracing protrusions and rubberized coatings and sleeves create a handlebar expander grip.
