The Powerslide XC Trainer Bronx uses a new generation of soft shoes that are firmer than ever before, but at the same time more comfortable. The skates are mounted on the XC Trail frame. The model is powered by V-Mart air time 150mm wheels. They provide a comfortable ride, absorb most shocks. These wheels have a wide profile and run smoothly on uneven surfaces. The Powerslide XC Trainer Bronx roller skates are equipped with Wicked bearings of the ABEC 7 series. They have a solid steel cage and 7 steel balls, which are perfectly adjusted to guarantee the lightest rotation. Japanese Kyodo oil was used in the production of bearings. Weight: 1870g For all wheels with a small radius, there is a slight deviation outside the axis of rotation during rotation. The reason is the valve, which must always be placed to one side of the wheel so that it is easier for the inflator to access the valve. The ratio of the weight of the valve to the wheel itself therefore causes a smaller misalignment of the rotation, which, however, does not affect the ride itself.
