The OS-99 is the lightest stem in the FSA line at 103-grams for a 90-millimeter, Made from 7050 aluminum alloy, it is constructed using a proprietary 3D forging process that uses slow forging speeds and high pressures to eliminate surface deformation. The forged faceplate has a serrated grip area to securely clamp on alloy or carbon handlebars. All edges are then radiused to eliminate potential stress points. For use on carbon steerer tubes, the clamping area is diagonally cut to better distribute loads. FSA completes the OS-99 with titanium hardware. The FSA OS-99 Stem retails for $99.99.
