The Cowbell 3 is 6061 aluminum alloy and the Cowbell 2 is 7050 aluminum alloy. The 2 is lighter, because 7050 has a higher yield strengh and can thus be made with thinner walls. With thinner walls, the bar can be butted and manipulated to offer more vibration dampening without affecting overall stiffness. 6061 is usually thicker with less butting an manipulation thus tends to have a harsher ride quality. This is something often overlooked in the world of aluminum bike components, and many pros run higher performance aluminum bars for security amd ride quality.
