Swix Roadline Classic has a newly-developed frame with a shape that utilizes the best properties of the aluminum material. This makes the roller ski feel like the feeling you get when skiing on snow. The combination of the new fork and frame increases torsional rigidity by more than 30% compared to the old Swix Roadline. All components and design are based 100% on all the innovations of the Swix Carbon classic. The fork, with CNC-machined axle fittings and tight tolerances, ensures optimal directional stability. The axles and the wheel system have been completely redesigned to remove protruding screws/nuts and facilitate maintenance and wheel replacement.
