The Sl-k series is the enthusiasts choice. Made up of components ideal for both road and cyclocross the Sl-k series represents the best combination of lightweight, strength and advanced technology for top performance. The Sl-k -20° drop stem is forged and CNC machined from aluminum, perfect for big wheels and long forks. The Sl-k seatposts let you choose between a seatback interval of and 0° of 20°. The Sl-k SB0 and SB20 seatposts are ultra light and stiff at only 222gr of weight. (27.2 x 350mm). Available also in the ITC (Independent Top Clamp) design for a rapid adjustment of saddle angle and position. The series is completed by the stainless steel Sl-k bottle cage and WE/Di2 seatpost battery adapter.


The lightest and fastest: these two words perfectly sums up what the K-Force series is all about. Including high-end AL7075/T6 chainrings and hollow carbon cranksets, the K-Force series represents the latest advancements in carbon composite and metal alloy technology. The OS-99 stem is 3-D forged and CNC machined from AL2014 and then combined with a carbon structure through CSI (Carbon Structural Integration) technology, a process that permanently bonds carbon to alloy to create a hybrid product. The K-Force light stem is lighter than ever at only 150gr for a 100mm length and features a monocoque carbon body plus an alloy faceplate. Topped off with a forged alloy Minimal Top Clamp, the three SB0, SB25, SB32 seatposts (for different seatback intervals) represent FSA dedication to advancements in ultramodern manufacturing. The K-Force Compact and New Ergo handlebars close the series are constructed from Kevlar-reinforced unidirectional carbon fiber perfectly balance weight, stiffness, and vibration.
