Federal Bikes Grind Wax Block Description: The Federal Bikes Grind Wax Block is 5.5 ounces of buttery smooth, good times designed so that it is ready to be used on both rails and ledges via a slick shape. Rounded on two edges, flat on the others, and small enough to carry along for the ride with enough material to last means that no matter what grinds you are looking to conquer, you'll be ready. Sometimes, the issue with a grind doesn't have anything to do with how slick the surface is. If your pegs are needing replaced, Dan's Comp has a large selection of BMX Pegs to keep you sliding through those grinds.
