Bont Spec-R Short Track Ice Speed Skating Blades

2013 Model. Runner length, 16.5". Blade thickness, 1.1mm. Weight, 15oz/blade (includes runner, tube, cup, bolts and nuts). Blade cross sectional depth, 19.5mm. Standard blade radius, 8m counterclockwise curve. Standard blade rocker, 21m. Blade material - 58 Rockwell hardness, Japanese Carbon Steel. Tube and bracket material - 6061 T6 Aluminum. Cup material - 7075 T6 Aluminum. Cup slot centerline spacing, 195mm. Mid-range of the Bont blade models. Exceptionally fine gliding blade. Blades are patented machine bent meaning that they have a slight bend cut in the tube for the steel so that you only need to slightly bend the blades. Therefore, the tube has less stress and less chance of it losing its bend like normal blades. Includes four extra tube towers and cup legs mounting bolts and nuts. The runners have been sharpened in an Ultimate Edge speedskating jig and oiled, then wrapped in paper and bubble wrap and placed in their packaging box. The short track setup included the blades being mounted to the Mariani Dogma Carbon 80 in-line speedskating boots, which are also being sold separately on this site under the same category and username, @alpine5.
