The R5x2CSTR is an upgrade caster for the R8RT
and R10RT. The custom-designed R-Trac Wide wheels feature low profile no-flat tires, lightweight but strong polymer hubs, low rolling resistance, pneumatic-like cushioning, vastly wider load dispersion
over soft terrain, and a stunning racing-style look. 5" x 2" brake casters are 50% wider than typical casters and can glide over soft terrain.
All casters are sold individually, but you must purchase (2) for use as an upgrade to the R8RT
