GC HD Frames 72mm w/alum H-block Silver

The HD frames are stiffer and more responsive than the typical UFS plastic grind frame allowing for increased energy transfer and prolonged frame life.  Interchangeable h-blocks offer the user options for whatever obstacle they are skating. Each H-block will work on both 60 mm & 72 mm frames in all lengths. A pair of plastic H-blocks and a pair of aluminum H-blocks are included in the scope of delivery
