Rotor Aldhu 2x Carbon Crankset A true upgrade The Rotor Aldhu 2x Carbon Crankset features the legendary modular design, abundant configuration options, and top-level performance that Rotor is famous for. This carbon crankset is 100g lighter than the already lightweight aluminum Aldhu 3D+ crankset, and tips the scales at a measly 555 grams, with stiffness increased by 11% vertically, and 36% horizontally over the aluminum. The performance of the Aldhu is augmented by 5 crank arm length options, a modular design with CNC'd direct mount chainrings in various configurations, and both standard or offset axle options to get the optimal chainline for any drivetrain. Who says high performance means compromising?Features Lightweight carbon fiber construction shaves 100 grams from the original aluminum Aldhu Increased stiffness from the aluminum crank, by 11% vertically, and 36. 1% horizontally, providing increased power transfer Modular design with direct-mount CNC'd aluminum chainrings, and offset or standard axles for optimal chainline Five crank arm lengths to accommodate every rider SPECIFICATIONSCrank Arm Length155, 165, 170, 172. 5, or 175mm Chainring Type Rotor Direct Mount, or 110x4 bolt pattern Crank Arm Material Carbon Fiber Chainline43. 5mm (Standard Axle) or 46mm (Offset Axle)Bottom Bracket Included No Intended Use Road Weight555g | Rotor | Aldhu 2X Carbon Crankset Aldhu Carbon Road 175Mm 52/36 | Aluminum
