The main wheels of a wheelchair are attached to the chair at a predetermined one of a plurality of camber angles differing by one or more predetermined angular measure(s). The apparatus comprises a bracket extending from the wheelchair's frame as well as a plurality of axle retainers disposed about and juxtaposed along the stub axle, the retainers used to mount the axle in the bracket. Switching from a first of two predetermined camber angles to the second requires removing the axle and retainers from the bracket, translating the axle either inboard or outboard (i.e., either toward or away from the center of the chair) by a predetermined amount, and reattaching the wheel to the chair. The operation may also involve adjusting the length of one or more of the bracket legs. Switching between camber angles preferably does not affect the height of the chair's seat or the position of the top of the wheels relative to the user's shoulders.
