We’ve reinvented the wheel! The patented CAMBA wheels provide all-terrain rolling performance, keep the cart balanced at all times and make it easier to pull or push over obstacles, up and down curbs and over rough terrain. The unique and patented CAMBA technology combines a hemispherical wheel with floating axles to provide great all-around performance across multiple terrains. The CAMBA wheel features an Active Variable Footprint whereby the point of contact on hard surfaces is optimized, and the wheel intuitively adapts to softer surfaces to create a wider footprint thereby spreading the load.
