A wheelchair has a frame including left and right frame members, each frame member having a first leg configured to support a seat, and a second leg configured to support front caster wheels, the first leg extending substantially horizontally and the second leg extending substantially downward from the first leg. The wheelchair also has a caster strut attached to the second leg of each frame member. The caster strut has first and second strut sections. The first strut section is fixed to the second leg and arranged substantially horizontally. The second strut section is arranged substantially vertically and provides, at a lower end, a mounting for the caster wheel. The caster strut further contains a curved section intermediate the first and second strut sections.
