Afterburner is our flagship aluminium riser bar and represents state of the art alloy manufacturing. The raw 7050-T6 aluminium is drawn into tapered-butted tubes and finely controlled for the wall thickness to cope with the different riding demands. Finally, a shot-peened surface treatment extends the fatigue life of the bar.
