The FSA SL-K Carbon Stem combines lightweight carbon fiber with the latest in alloy forging technology to give you the stiff support you demand without weighing you down. The SL-K carbon is built with a mix of carbon fiber composite and CNC machined 2014 aluminum. The aluminum stem body is 3D forged, which allows FSA construct a more rigid stem with less material to reduce weight. For added weight savings, the SL-K features a carbon fiber faceplate with chromoly hardware. The SL-K has a 40mm fork-clamp stack height with a six-degree rise, and it’s compatible with 1-1/8in steerer tubes and 31.8mm clamp diameter handlebars. And to keep you on point, FSA includes clamp-to-clamp model graphics that run inverse of each other.

  • Familiarity: I've put it through the wringer

First, the SL-K Carbon stem is mostly aluminum-just the face plate is carbon. It does it's job and seems stiff enough but I think there are a lot of choices in this price range. And note the rust in the bolts-the only thing rusted or corroded on my bike-cheap materials??
