Ground Control HD Aluminum Frames 72 mm sizes are here. 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 72 mm frames in all lengths.
51.5mm frame height / 41mm frame width/ 114mm middle wheel split
Lengths: 261mm, 270mm, 283mm
* Length refers to the wheelbase - the length from the center of the first axle to the fourth.
Anodized Black comes with black aluminum block and white plastic block. Silver comes with silver aluminum and black plastic block. Each pair includes both 8 steel axles with 8 - 8mm bearing spacers. Hblocks and axles are also available separately.
