You probably don't need anyone to tell you about the benefits of carbon fiber, but we'll do it anyway: it's light, strong, and, when blended with Kevlar, as in the FSA SL K Compact Carbon Handlebar, seriously tough. So, if you're looking to lighten your setup while boosting durability and aesthetics, the SL K is a killer place to start.By constructing the SL K as a single piece of material called a monocoque, if you care FSA was able to ensure extreme rigidity for powerful sprinting and precise handling. Carbon dampens road vibrations and keeps the weight low, and Kevlar fibers reduce fatigue, so your bars will stay rock solid longer than pure carbon bars. FSA was also careful to strength the SL K in key areas, most notably under the clamps, so the stress points are extra beefy. Clamping areas have also been textured to increase security, and FSA included internal cable routing for a sleek, smooth look and more comfortable hand positioning.
