Ground Control HD2 Aluminum Frames, Available in both 60mm & 72mm sizes, the HD2 is a reinforced version of the original HD frame.

• (72mm listed separately) For the HD2 frame, GC has increased the wall thickness of both the 60 and 72mm frames to increase their stiffness - increasing overall strength and allowing for increased energy transfer, equaling more speed at the park and in the street.
• Countersunk axle holes help protect axle bolts from wear.
• The HD2 comes with interchangeable plastic & aluminium h-blocks, offering the option to run either nylon of alloy to best suit the kinds of obstacles you are skating.
• H-blocks will work on both 60mm & 72mm frames in all lengths.
