The patented RUNDLESKI™ was designed with two goals in mind: to reduce road vibration transmitted to the skier, and to simulate the feeling of compressing a skate ski on snow. According to Rundle Sport the suspension system of the RUNDLESKI™ significantly reduces the fatigue and strain on the athlete’s legs. It also minimizes the rollerskis from skipping and chatter by maintaining consistent ground contact. The rollerskis offer a maximum of 16mm of suspension with nine levels of stiffness and three options for wheel speed preference – check out the vids below and visit the site here.
