Blade Radius (rocker) can be selected to meet your style or preference of skating. Work includes height matching of the runners for sets that have been previously setup from factory original, centering of the radius, and fine grinding a smooth radius the entire length of the blade. We thoroughly gauge check them and sharpen out the grinding marks. Choice of several of the most common constant or progressive radiuses (rockers) are available. Contact us for custom rockers or for blades that have factory edge and we can advise better on cost estimates.
