The crankset is made from lightweight aluminium alloy and features hollow arms. The resin ribbing helps to further reduce weight and the black anodised finish, gives the crank an elegant look. The design ensures smooth and efficient power transmission to the drivetrain and allows the chain to jump smoothly between the sprockets. The use of Hollowtech II technology has resulted in an optimum balance of weight, stiffness, strength and rotational performance. The technology uses ultra-lightweight hollowtech mechanical cranks and a proprietary forging mechanism, all of which is precisely balanced and well sealed.
