Rotor ALDHU Direct Mount Round Chainring - 110 BCD - 50/34T

Introducing the new ALDHU 3D+ one-piece, direct mount chainring. 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. Our new model name comes directly from our racing heritage. It is an abbreviation of Alpe d’Huez to commemorate ROTOR’s first iconic victory at the Tour de France with Carlos Sastre.
