This is Marwe's skate wheel with ratchet functionality. This ads a directional resistance to your skate roller ski setup, enabling you to ride with a kick-back technique. You get a choice of 3 hardness' that you can then utilise to get more out of your workout by for instance going with the slow version. The Ratchet wheel is always installed on the front-end of Marwe Skis.
The rubber used is Marwe's popular blend that yields durability and good wet grip capabilities.
The wheel comes complete with bearings and an axle pre-installed.
