Product information "GC HD Frames 60mm 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
