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. Weight: 168 g for a 52/36

excellent upgrade from DuraAce Crankset
I was looking to upgrade my old DuraAce 50/34 crankset and settled on the Rotor Chainring/Crankarm/Spindle in 24mm so I can keep my same BB. It is very easy to install and is lighter and stiffer than the Shimano as well as being very sleek and elegant to look at. The workmanship is top-notch and performance is superb. Being Made in Spain is also nice as I try hard to avoid Made in China for both quality as well as ethical concerns.
