Introducing the ALDHU® cranks, ROTOR’s lightest cranks ever. The innovative modular structure, makes each component individually available to accommodate the current spectrum of riders and bike standards. If you need a 155mm crank arm now, and a 160mm later, you can separate the unit and mount your new arms on with minimal effort.
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.
A 30mm axle make the crankset stiffer and lighter than previous generations and has a low Q-factor of 140mm, ensuring a perfect position in the bicycle for TRACK and Fixed users. Given the unique requirements of track cycling and fixie riding, you need a super stiff chainring able to respond to your fast-twitch muscle action and high power outputs. Aero, stiff, and crafted especially for track, our Round rings with 144BCD and designed to work with a 1/8″ chain width for your track or fixed-gear bike provide the performance benefits inherent in round rings with the dependability you should expect from your chainrings.
This system must be used in conjunction with a 68mm bottom bracket shell and the specific Rotor Track Bottom Bracket.
