The standard Grind Rail from FreshPark combines all the benefits of a square and round rail. Balancing is a breeze due to the flat top, but its rounded sides allows for realistic rock-ons. Its adjustable height makes learning tricks easier, and allows the rail to be ridden in more ways than a flat bar. Up/Down rail on flat ground, down a curb, up a curb, or even taking it to your local skatepark to create unique combo obstacles. The possibilities are endless. You can also purchase more than one and connect the two rails to make for a fun longer rail.
