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, finely controlling the wall thicknesses to cope with the different demands of different sections of the bar at minimum weight. A shot-peened surface treatment extends fatigue life. It's available in three widths from an XC 630mm to an AM-friendly 740mm. All have a subtle 15mm of rise which is just enough to give a slightly more commanding riding position than a flat bar on the same bike.
