Joost is proud to present to you his sponsors for the upcoming season! Some of them are familiar, some of them are new.

The support comes from two directions. There are team-sponsors, companies that have committed their name to the R.S.P. Mountainbike Team, and there are personal-sponsors.

New personal sponsors:
- Leatt Brace
- Tunderwear

If you want sponsor support Joost or his team, please contact Thirty7even, by using the contactform on this website.

Maybe you're just a big fan of the sport and this athlete, than there's a great opportunity to show your support by becoming a member of the Club 100.
