Verwende die Achse für ein Canyon…

Verwende die Achse für ein Canyon Neuron:on AL 8.0 2025 und ein Spectral AL 5.0 2018, um einen Thule Chariot 2 Sport zu ziehen. Hat alles super funktioniert und gepasst.

Nachhaltig verpackt

Sustainably packaged.

Nature is very important to us. That's why we avoid unnecessary plastic and rely on packaging material made of paper or cardboard. If your package does contain plastic filling material, this is material from our suppliers which we have reused.
