Renthal machines the Apex Stem from a solid piece of aluminum, so you know that it's equal to whatever abuse you throw at it on XC drag races or enduro bombing runs. The oversized clamping hardware secures the bar in place with a sort of 240-degree hug, virtually eliminating the targeted stress points that can contribute to bar failure. The Apex also has an artistic side, though, courtesy of its Art Deco styling, so it classes-up your ride even while you're tearing down lines.
