If you need a rigid support without the carbon fiber price Please note the FSA SL-K SCR stem. This rigid rod combines 3D forging and CNC machining to provide rigidity close to the same level as carbon and titanium while keeping the weight as low as possible. The rod is made of aluminum 2014 and it uses a process that starts with a single aluminum ingot which is drilled out and takes on an internal shape; ultimately improving the aluminum grain structure eliminating the use of welds and significantly reducing weight. Your benefit: increased rigidity , weight comparable to carbon fiber at a significantly lower price. To maintain your weight loss the SL-K uses a carbon fiber faceplate with chrome-molybdenum hardware.
