Racing wheelchair rear wheel alignment

This technical note describes a time-saving device for aligning the rear wheels of a racing wheelchair. The newly-developed analog alignment device is compared to the now standard discrete alignment device. The analog alignment device is found to reduce the time needed to align the rear wheels by nearly 75 percent, while increasing the accuracy of the alignment. The device does not noticeably alter the performance of the racing wheelchair and, if installed properly, the device is sufficiently resistant to fatigue.
