Power your ride with Campagnolo's Centaur Power-Torque Crankset. It sports Campagnolo's lightweight Power-Torque integrated spindle design for optimum stiffness and efficiency. Bottom-bracket bearings are included and fit into outboard cups (sold separately). Plus, the design's stiffness allows the aluminum crankarms to be thinner and lighter than ever before. What's more, the Centaur cranks sport finely-machined and pinned chainrings for impeccable shifting.
