A lightweight wheelchair has adjustable wheel camber, adjustable toe-in/toe-out positions, and front-to-rear adjustment of a wheel assembly relative to a frame (40a,40b). The wheel camber is changed by removable camber tubes (50a,50b) having plugs (54) in opposite ends with different angular relationships. Each camber tube (50a,50b) can be removed from an axle tube (22), rotated through one hundred eighty degrees, and reinserted to change the wheel camber. The location of the angular recesses in the camber plugs (54) addresses minor toe-in/toe-out adjustments while rotation of the axle tube (22) provided with indicia (82a,82b,84a,84b) ensures that proper toe-in/toe-out adjustment is provided for larger wheel camber adjustments. The front to rear location of the wheels relative to the frame can be adjusted via a single fastener (30a,30b) on each side. The track width of the rear wheels can be adjusted in response to the change in wheel camber by changing the extent of insertion of the camber tubes (50a,50b) into the axle tube (22). <IMAGE> |
