The Ground Control 72mm HD2 Frames with aluminum frame walls are thicker and stiffer than the original HD, increasing both overall strength AND energy transfer. Aluminum is light, responsive, and durable. Comes with both plastic and aluminum h-blocks (same as used on the GC 60mm HD2). Countersunk axle holes help to protect bolts from wear.
Available in three different sizes. The longer is more stable, whereas the shorter is more agile. Choose based on preference as well as boot sizes. As a guideline boot sizes 9.0+ often choose the Large or XL. The frames come with one-piece 8mm aluminum axles.
