Description

ROTOR crank axle ALDHU 3D + Vegas t for race

With the ALDHU 3D +, ROTOR brings the lightest crank in its history to the market. The name is an abbreviation for the legendary Tour de France rise of Alpe d'Huez, where Carlos Sastre laid the cornerstone for the Tour overall victory in 2008 with Rotor Q-Rings and thus gave ROTOR one of the biggest victories in the company's history.

For the greatest possible adaptability, the ALDHU crank system has a modular design. Thus, the chain line for disc and rim brake hubs can be adjusted via 2 different shafts and the 110 mm 4-hole Spider can be exchanged for ROTOR's new Direct Mount chainring combinations. For optimum adjustment of the oval ROTOR Q-Rings chainrings, the OCP system (Optimum Chainring Position) has been further refined. Through a combination of different positions of the crank arms on the crankshaft and a fine-styled Spider recording the position of the chainrings can be adjusted in 1-degree increments. For the adjustment and assembly of the chainrings and the crank, only a 10-millimeter hex key is necessary.

The crank arms made from ultralight 7055 aluminum are manufactured using Rotor's proven Trinity Drilling System. Over the entire length of the crank arm material is removed from the central, neutral fiber of the crank arms in 3 channels. This material contributes only slightly to the load capacity of a component and can be omitted without negative consequences. The necessary rigidity and stability is achieved with lightweight construction over large outer diameter.

The shafts are 30 mm outside diameter BB30 and can be driven via corresponding bottom bracket in frames with BSA, BBright (Cervélo) and BB30 bottom bracket.

NOTE: Contrary to the illustration, only the crank axle is supplied. The ALDHU crank arms and matching chainrings can be found in our shop.
