The PROTO SCS is the original and first Standard Compression System that has become the industry standard since its inception. Created, designed, tested, manufactured and Patented (US Patent #8657522) in Vista, CA by Andrew Broussard. Andrew is one of a handful of riders who got fed up with incompetent, faulty and flat out bad scooter designs that were on the market back in the day. His ideas became his realities through the creation of parts specifically designed to make a stronger, lighter and better performing scooter. Trial and error evolved each design which lead to the creation of the brand known as PROTO. Since its inception in 2008 PROTO has been the bench mark that all others have followed and evolved from. PROTO prides itself in being on the innovative forefront of freestyle scooter product development and design. The 4 Inch PROTO Scooters Full-Knuckle SCS works with both Standard and Over-Sized handlebars. Made in San Diego California, this is not only the original SCS clamp, but still the strongest and most reliable SCS made. This SCS Full-Knuckle is built to perform and last and carries a Lifetime Warranty against cracking. PROTO – Stickers included! Ride the original, ride PROTO.
