Rotor ALDHU Cranks 172.5mm

Introducing the ALDHU cranks, ROTOR’s lightest cranks ever. ALDHU gave Rotor its first victory in the Tour de France: Carlos Sastre won legendary Alpe d'Huez stage, hence the name of its most advanced cranks. Following his example, Rotor wants you, too, to be able to achieve your most ambitious cycling goals.

Rotor Component Technologies was founded in the School of Aeronautical Engineering in Madrid in 1995. The designers decided to stablish a company to complete this product development and start a business venture. The early version of the ROTOR System became available in 1998, being manufactured by the Spanish high end component manufacturer.

In 2001 they launched the RCK so all cyclists could take advantage of the biomechanical benefits offered by ROTOR System using a conventional bicycle frame. In 2015 the company took a huge step by introducing the oval shaped chainring.

The aim of the company is to offer solutions for cyclists and to improve the performance of bicycles with help of high technology. The cyclists find problems and propose innovative solutions. They have repeatedly demonstrated that with technologies like the ALMA (Appropiate Lightweight Material Aplication) and the CCC (Closed Clamp Concept), the bicycle market can be revolutionized by fresh and powerful ideas.

Professional cyclists, world champions, teams of the UCI and cycling enthusiasts use the ROTOR products in their competitions and trainings. The evolution in the products comes from information provided by cyclists themselves.
