Achim Kujawski is putting on the second Verthaus jam in Oberhausen with support from adidas, Red Bull and Eastpak . Last year's edition was a success and all vert riders had a great time. It doesn't happen too often that you can just ride with your friends at an indoor place on a decent ramp (it's a vertical-Red Bull halfpipe).
It's invite only so be nice to Achim next time you see him if you want to join the session. Peter Geys, Sven Kabusch, Matt Fairbairn, Tim Eichert and Jean Marie Baertsch are already on the list. Click the flyer for more info or contact Achim through the Verthaus website.
