Rotor ALDHU 3D+ Track 5-Spider incl. 30mm axle

Suitable for the ROTOR ALDHU 3D+ Track crank - Track Spider 144/5 including track axle for maximum rigidity.

The high-quality and light spider/axle set rounds off the modality of the ROTOR AlDHU products. The set consists of a spider with multiple teeth and a 144mm bolt circle with 5 holes so that the lightweight Aldhu/Vegast crank arms can also be used on the track. You also get a matching, lightweight aluminum ROTOR ALDHU track axle. You can combine these modularly with the new Vegast or ALDHU crank arms. The Track crank axle ensures a Q-factor of 140 mm and a chainline of 43.5 mm, which is ideal for use on track bikes or fixie bikes. The larger diameter increases rigidity and enables better power transmission with a lower weight. To use the Track axle, the ROTOR Track bottom bracket must be used.

The ROTOR ALDHU 3D+ crank system for racing bikes was created together with the ROTOR VEGAST and shares its innovative and modular design. However, the ALDHU 3D+ has been extremely trimmed to be lightweight and, with its crank arms that weigh just 182 grams, offers the extraordinarily high rigidity of the top class. Comparable crank systems from other premium manufacturers are well above the system price of the ROTOR ALDHU 3D+. Assembly can be completed in minutes without specialist knowledge or special tools and changing the chainrings is just as easy.

The ALDHU, based on the ROTOR 3D+, is a fully modular system and completely dispenses with the set of left crank arm and combined axle/spider/right crank arm that has dominated for decades.

The Track Spider/axle can only be used with the ROTOR Track bearing 30mm, as the axle is shorter than the road version!
