With multiple World Championship medals, EWS series wins and Olympic gold medals to its namesake, the XX Eagle DUB Crank is proven as the pinnacle. Inside, it has been engineered with an ultra-strong but ultra-light design that utilizes carbon fiber with a hollow core – still the lightest ISO certified crank on the market, maximized for title winning stiffness. Now pair it with the remarkable new XX SL Eagle Transmission (T-Type) direct mount chainring, and the spotlight turns from its performance to its appearance, because it absolutely looks like nothing you’ve ever seen before.
