Go Project has gone to the design board with all the needs of the modern skater and came out with these incredibly well designed bangers. These come in a larger then normal (for anti rockers) 48.5 mm diameter, to keep up with the ever increasing amount of larger sized (Esp the 60-72 mm range!) aggressive wheels out there, to create a perfectly shaped and proportionate groove to lock on without fail.
They use a newly formulated urethane for insane hardness that isn't plastic, and comes with the bearings already in, for super performance. Step up your royales and slap these on.
