FSA Gossamer 386EVO 11-Speed Road Double Chainset

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 FSA's 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 FSA's ABS system – Asymmetric Bolt Spacing with the chainring bolts strategically spaced to provide optimum strength from a 110mm BCD. Gossamer fits any combination of bike, rider and riding styles.

Technology

An 86.5mm Wide PF30 BB Designed For FSA's BB386 Evo Crank Sets

All for One, One for All: FSA’s latest evolution in bottom brackets spans press-fit and threaded standards. With the proper BB and/or adapter, this crank will work with almost any BB shell standard. 386EVO’s symmetric BB shell has the same overall width of a BSA BB including the cups. This allows the ultimate optimization for stiffness of the frame-shell-crankset assembly. The longer 30mm spindle and a wide variety of optional spacers and bottom brackets provide unmatched adaptability for nearly all bicycle frames.

New FSA Gossamer BB386Evo Crankset

The Gossamer Pro ABS Crankset is the pinnacle of alloy crank technology and uses technology learnings from FSA's 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.
