For some components, 'lightweight' and 'carbon' can be dirty words. In the early 2000's weight-weenie craze, the peloton suffered under the malleable malfeasance of poorly designed, lightweight cockpits. Well, those days are finally past us, in part, because of pristine designs like the FSA K-Force Light Stem having taught the cycling world a very important lesson -- innovate or don't bother. The new K-Force Light does just that by using a total carbon and titanium construction that offers up rigidity, style, and massive weight savings.FSA's K-Force Light Stem features a 100% monocoque carbon fiber body construction. The new design achieves an equilibrium between weight-savings and ride quality without sacrificing on either polarity. The K-Force Light provides a stiff and direct platform to the bars, while weighing in around an alarmingly low 149g. And while most weight-shaving stems feel more malleable than rigid, the K-Force's design avoids the wet-noodle-zeitgeist by eliminating any steel or alloy from the stem. You heard that right. The K-Force Light uses only titanium hardware to secure to the steer tube and to attach the carbon faceplate. The FSA K-Force Light Stem is available in four sizes from 100 to 130mm. Please note that this stem is only compatible with 1-1/8in steer tubes and 31.8mm clamp diameter bars.
