Caster wheel The caster wheels are aligned to the rear wheels by means of a curved caster wheel arm to give stability and balance without increasing the width of the wheelchair. The size of the caster wheel is 6”- 1-1/4” so that it is possible to manoeuvre small obstacles such as curbs, single tread which is approximately 6” or 150mm high. The caster wheel fork follows the similar geometrical language as the bracket connecting the backrest and the chassis. It is provided with 3 slots to adjust the height and tilt of the wheelchair. Caster wheel components: • Smooth, gray solid pneumatic tire with three spokes, to absorbs shock and vibrations associated with rough surfaces. • 5/16 Bearing, • 1-3/16” aluminium anodized hubs help to avoid scratching.
