Not ready for carbon? The Gossamer is a high-end crankset for lovers of alloy, and with an impressive history of wins on the brutal cobbles of the Paris-Roubaix, it needs no further explanation.
Yet the details can’t be ignored. And not just because of its new smoothly integrated design. The cold-forged aluminum arms are heavily scalloped for the maximum strength to weight ratio, while the versatile BB368 spindle is forged from an even stronger alloy. The 30mm spindle is compatible with English Threaded, SMN Press Fit and BB30 bottom brackets with just a few simple spacers.
The chainrings are CNC machined from still-tougher 7075 aluminum, and ramped and pinned for the most rapid, precise shifting. Finally, the chainring bolts are chromoly steel for exceptional strength. The Gossamer crank is an impressively lightweight 751g.
Boosting stiffness further is our ABS system – Asymmetric Bolt Spacing. A fifth chainring bolt hidden behind the driveside crank arm delivers extra strength just where it’s needed to resist power strokes and keep shifting ultra-crisp. Available in four crank lengths and five gearing options, the Gossamer fits any combination of bike, rider and riding style like a glove.Key Features
