Alpine trucks are manufactured with the highest technology. You can choose between two concrete surf modes, two different combinations: K1 and K2.
In K1 mode the skateboard has stability at the rear while the front allows for greater turning, which makes this option more aggressive concrete surfing. Just a little spin of your body and the skateboard goes into motion. The pump is amazing and you will find that there is no need to put your foot down even over long distances.
Already with the K2, both trucks have the same feature. There is a patented internal limiter system on the center pin allowing turns without the worry of the wheel touching the shape. In this mode the feeling is of a line surfing with more rounded and open curves.
Take a test and feel the surf!
