Rodby has been commissioned by the University in Östersund to build the largest model of treadmills, a custom-designed and custom-built RL 5500E, with a unique tilting feature where the band can be controlled so that it is both uphill and downhill. The treadmill will be placed in a large wind tunnel and used in elite sports research for cross country skiing. The treadmill is specially constructed in galvanized steel for use in a simulated outdoor environment.
