The antitipper on the back of the Hammer chair prevents back flips, thereby letting players focus on the game instead of the ill effects of gravity. The rigid picker front of the Hammer works as a sort of bumper. The Hammer's camber plate (shown with the wheels off) lets players adjust the angle the wheels make with the ground. Wheel camber lets players turn easier and maintain stability on impact. Spokes of Spinergy Spox on the TiSport BB chair are made from Vectran fibers which bend but maintain stiffness. They have twice the tensile strength of steel, a third the weight, and they act as shock absorbers. The TiSport BB is built from titanium tubing to better absorb shock. The TiSport BB has a standard flip-up antitipper as shown here, or an adjustable titanium fifth wheel. The Leader from New Halls Wheels is a racing chair that features a unicrown fork for maximum aerodynamics and speed. There was a time when people confined to wheelchairs didn't go out in public.

People with all types of disabilities lead active lives and participate in many activities, including athletics.
