The Smile Seat Clamp System (SSC System) was designed and developed to be simple, light and functional. It means you do not need extra parts to have your seat tube tighten in the frame, you do not have to worry if the seat will move when the bike falls down or if the clamp screw will break when you'll tight hard.
After doing a BMX 'zine for ten years (1987 - 1996) FATBMX made it on the internet. The year was 1998. Here to stay.
