The Bearpaw/Ski provides an increased footprint along the full-length of the skidtube and features 2 wearplates for additional wear resistance. The polymer resists cracking, chipping and breaking and the machined construction ensures consistent and deliberate load transfer. This flexible material deflects under high-point contact loads when landing on rocks or roots; its inherent memory ensures the Bearpaws return to their original shape upon take off. *19" wide footprint.
