The majority of chairs used in the sport today are constructed from Titanium or aircraft aluminum and include an additional 5th wheel for added stability and mobility. The front bumper is designed so that it will not lock with or be held by the opponent. The angle of the wheel base or “camber” is optimal for each athlete to allow for stability and quick turns. The wheels on the chair often now use cables rather then the traditional steel spokes as the cables are 3 times stronger and 50% lighter then steel.
The design of the chair takes deign aspects from equipment used in many other sports to include cycling (cables and frame design) roller blade and skateboarding (fifth wheel design) and Snowboard bindings (strap at the waist to hold the athlete in the chair). The high end basketball wheelchairs are expensive and range from $2500 to $5000 in price.
