A lightweight aluminum Core is the heart of the system, reusable and stronger than ever. Removable Frame Walls then mount to the sides, providing the smooth grinding surface you’ve come to expect from Fifty50. The frame walls are attached to the Core by their heat treated 8mm axles and aluminum frame spacers. All included at the price of a normal UFS frame.

New Core System frame design, freestyle frame includes aluminum Core, Frame walls, 8mm Super Axels and mounting hardware.” -RollerWarehouse.com

this frame is strong and sturdy. from what i have done w/ these frames they are good i have had them for about 3 weeks now and i love them. the oversized h-block allows you to lock into grinds from any position. the only problem i have had w/ these frames is when i first got them the axel was hard to get into because the plastic frame wall didnt exactly line up w/ the aluminum core. after a few minutes of beating and squeezing i managed to fix the set-up. i give these frames and over all 8 out of 10. they are great for people who love to do ledges, rails, grind coping, airs, gaps and everything else i highly recomend these frames.
