Fan Belts (Cogged)

V-belts for Cars and Vans

[Translate to English:] optibelt MARATHON I Keilriemen – flankenoffen, formgezahnt


The MARATHON 1 has excellent tension behaviour with low-stretch.

This, together with the section accuracy, means it runs extremely quietly when it rotates alternators, water pumps or air conditioning compressors.

Due to its maintenance-free high performance capability, continuous use of the MARATHON 1 is particularly cost-effective.
