The AV10107 machined 13mm pistons for the new AE 13mm shocks are the thicker 2.5mm style. They offer a conventional setup but with a perfectly machined round piston and square 90° edges for a tight-fitting piston that has little blow-by creating more pack on jumps. The AE piston has a slightly rounded outer edge and the holes are chamfered which results in harder landings. Over the years here at Avid, we have developed a process of keeping all the edges sharp with little to no burrs to keep your confidence high when landing big jumps.A square 90° angle on the piston edge and holes is one of the most overlooked advantages of a machined piston. Our pistons have very sharp edges and sometimes this leaves a small amount of flashing that can easily be removed with your fingernail. Do NOT use a nail file or anything abrasive.
