Our long sought after G-Blocks are back for a limited release! These freestyle grind blocks fit seamlessly into the OG frames and simply make it easier to do all h-block groove tricks. You will never stick on those types of grinds with these blocks. They can also be used with just a single G-Block in the 2nd or 3rd wheel position for an easier grinding "tri-rocker" setup as well. Available in sets of 4 or sets of 2.
