Super lightweight in 7 lengths for a perfect fit

XRD SL stems are created with the latest 3D forged, 7050-T6 aluminum alloy. They are designed with a ‘V’ angle bolt system for a force fit, making it a tight fit around the bar without having to over tighten and stress carbon bars. This creates more friction force and generates a clamping lock.
