GC HD Frames 72mm black

GC HD Aluminum Frames in 60mm & 72mm.  Thicker and stiffer frame walls increase overall strength, allowing for full energy transfer, equaling more speed and responsiveness at the park or in the street. Countersunk axle holes help protect steel axle bolts from wear.  Included plastic & aluminum h-blocks offer options for all kinds of obstacles. H-blocks are compatible with 60mm HD2, 72mm HD2, and FLT4 frames.
