Crankbrothers, the Californian brand producing mountain bike components, is the promoter of Trails and Bike Parks Partnership. It runs the global project for the maintenance of mountain bike trails and parks together with a network of local partners.

The project consists of a series of donations to mountain bike associations. The proceeds are used to mark trails and paths, clean them and make them accessible to all riders. 

Currently, the Trails and Bike Parks Partnership includes Massa Vecchia and the Paganella Bike Park in Italy, the Geisskopf Bike Park and the Willingen Bike Park in Germany, the Petzen Bike Park in Austria, Free Motion in Spain and Riveter in the USA. Over the years, these organisations and locations have become reference points for the international mountain biker community.

Selle Royal Group invests in the Trails and Bike Parks Partnership in order to support and promote mountain bike communities around the world.
