Simply put, the FL1.5 is one of the finest alloy stems on the market. It is 3D net forged from 7050 alloy then anodized in flat black. The squared off and somewhat rectangular body profile and shape adds plenty of stiffness. The face plate is a wide 4 bolt unit to provide stiffness and durability, not to mention quick bar swaps. Bolts are black anodized to match. The clamp diameter is the industry standard 31.8mm diameter to fit any modern handlebars. Select your length.
