We keep seeing more and more of the peloton reverting back to the tried and true reliability of aluminum stems, and the FSA SL-K Carbon Stem makes a good argument for why. Pairing the latest in alloy forging technology with lightweight carbon fiber, the SL-K Carbon improves on the past without abandoning the future. With a foot on each side of the line, FSA provides a stiff support for the handlebars at a weight that's in line with carbon and titanium. FSA's SL-K Carbon Stem is constructed from a mix of CNC machined 2014 aluminum and a carbon fiber composite. To guarantee rigidity, FSA 3D forged the aluminum stem body. This process starts with one ingot of aluminum that gets bored out and shaped internally; ultimately improving the aluminum's grain structure, eliminating the use of welds, and drastically reducing weight. The benefits to you are a heightened stiffness, with weight comparable to carbon fiber, at a considerably lower cost. To maintain the flow of weight savings, the SL-K uses a carbon fiber face plate with chromoly hardware. The SL-K Carbon features a 40mm fork-clamp stack height with a 6 degree rise. FSA has included clamp-to-clamp model graphics that run inverse of each other to keep the aesthetic unchanged whether you slam the stem or run positive rise. It is only compatible with 1-1/8in steerer tubes and 31. 8mm clamp diameter handlebars. The FSA SL-K Carbon Stem is available in five sizes, from 90mm to 130mm, and in the colors Black and Black/white.

FSA proudly proclaims that the bottom bracket in the FSA SL-K Light EVO386 is the last evolution of the BB standard. Given the multiplicity of so-called bottom bracket standards these days, this is a bold claim. It may have a point though, as the BB386 is really a series of adapters that plug into the most common versions of bottom brackets in order to accommodate the EVO386 cranks. Like its K-Force relatives, the SL-K's crank arms are molded around two tubular bladders, so the structure is buttressed-up with a thin, central sheet of material that runs the length of the crank. The cross section resembles a peanut, and the result is a lightweight crank arm that doesn't skimp on power transfer. This power transfer is further complemented by the SL-K's impossibly smooth and durable ceramic bearings. Ceramic can withstand even industrial applications without flinching, so for a bicycle, they're the bearing equivalent of spinning up on clouds. The wider, 86 millimeter spacing pushes the contact point with the pedals out slightly. Since the bottom bracket extends further, the crank arms don't have to bend as much to provide ankle clearance on the frame. That means less material, so it saves grams, and higher torsional stiffness because the crank arm itself is straighter. You know how bowed seat stays provide compliance to absorb road impact? The same is true of bowed crank arms, but the extra compliance works against you by flexing, which hampers efficient power transfer. Given the flexibility of BB386, the SL-K Light cranks are future-proof. They'll travel with you from frame to frame, and -- by installing your choice of FSA chainrings designed to work with Shimano, SRAM, or Campagnolo -- drivetrain to drivetrain. No matter what changes you make to frame or groupset, you'll never be without the SLK Light's lightweight efficiency again.
