Rotor Bike Components DIRECT MOUNT Round Chainring 50/34 ALDHU

The Direct Mount is CNC’d from a block of 7075 aluminum to save more than 30 g over a standard chainring combo which, together with ALDHU crank arms, becomes ROTOR’s lightest crankset ever. The ALDHU 3D's innovative modular structure makes each component individually available to accommodate the current spectrum of riders and bike standards.

• Lightweight, single-piece construction reduces bulk and streamlines
• 7075 aluminum construction is light, stiff, and reliable
• Available in sizes to fit any drivetrain needs from race day to gravel
