Kit Includes: Set of Ground Control HD2 60mm Aluminum Frames, 8x GC 60mm 90a Bullet Wheels, & 16x ABEC 5 Bearings w/ bearing spacers.

The HD frames are stiffer and more responsive than the typical UFS plastic grind frame - allowing for increased energy transfer, equaling more speed at the park and in the street. Countersunk axle holes help protect bolts from wear. Interchangeable plastic & aluminum h-blocks offer options for all kinds of obstacles. H-blocks will work on both 60mm & 72mm frames in all lengths.
