16mm Ae 5 Hole Fat Boys [2.2mm] Piston Set

The Schelle Fat Boys piston lineup is built around the concept that a thicker piston will limit flow around the outside forcing oil through the valving holes. For bumpy conditions, the 2.2mm versions are milled out in the center, so the valving path is only 2.2mm tall, reducing pack for bumps but keeping the outside height tall so that the suspension won't flutter, and can pack properly on big jumps. It gives the best of both worlds for lower grip. .. great bump handling while still packing up for the larger jumps.
