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. 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.
