New FSA Gossamer BB386EVO Crankset

The Gossamer Pro ABS Crankset is the pinnacle of alloy crank technology and uses technology learnings from our K Force Light and SLK ABS cranksets.

Using lessons learned from the development of the K Force Light ABS crankset the Gossamer provides the optimum combination of stiffness and weight reduction to provide the best pedalling platform in an aluminium crankset.


Not ready for carbon? The Gossamer is a high-end crankset for alloy lovers. With an impressive history of wins on the brutal cobbles of Paris-Roubaix, it needs no further introduction - yet the details shouldn’t be ignored. The cold-forged aluminum arms are heavily scalloped for the maximum strength to weight ratio and the versatile BB368EVO spindle is forged from an even stronger material. The 30mm BB386 EVO spindle is compatible with virtually every frame standard available by choosing the appropriate BB from our easy-to-use BB chart. The chainrings are CNC machined from still-tougher 7075 aluminum, then recess-machined and pinned for rapid precise shifting. Boosting overall stiffness our ABS system – Asymmetric Bolt Spacing with the chainring bolts strategically spaced to provide optimum strength from a 110mm BCD. Available in four crank lengths and five gearing options, the Gossamer fits any combination of bike, rider and riding styles.
