Not ready for carbon? The Gossamer is a top-of-the-range crankset for alloy enthusiasts. With an impressive history of victories on the brutal cobbles of Paris-Roubaix, it needs no further introduction - but the details shouldn't be ignored. The cold-forged aluminum arms are heavily scalloped for maximum strength-to-weight ratio, and the versatile BB368EVO stem is forged from an even stronger material. The 30 mm BB386 EVO spindle is compatible with virtually all standard frames available by selecting the appropriate spindle from our easy-to-use spindle chart. The chainrings are CNC machined from even stronger 7075 aluminum, then recessed and pinned for fast, precise movement. Our ABS system increases overall rigidity - Asymmetrical bolt spacing, with platen bolts strategically spaced to offer optimum strength from a BCD of 110 mm. Available in four crank lengths and five shifting options, the Gossamer adapts to any combination of bike, rider and riding style.AL6061/T6 forged aluminum cranks. Forged axle AL7050 BB386EVO.
