Abstract
A racing wheelchair is disclosed. The racing wheelchair may have a pair of rear wheels and a steerable single front wheel. The rear wheels may be independently driven by a lever, through a derailer and a chain, such that pushing one of the two levers will move one of the wheels but not the other. The front wheel is steerable by twist grips located at the removed end of the levers. Brake assemblies and shifter assemblies of the derailers are located adjacent the twist grip, and may be rigidly mounted to the push lever or mounted to the twist grip to rotate therewith.
