PROTO – 3.5″ Sentinel SCS (Silver) Scooter Clamp

The PROTO Sentinel SCS is a silver-colored scooter clamp that is the next generation of Standard Compression System (SCS). It is 3.5″ tall and offers 2″ of handlebar support, which is over 30% more than a 3″ SCS. It features larger 8mm bolts with 6mm allen drives and an offset slot that provides 25% more threads for increased torque and decreased chance of stripping. It is tapered at the top and base and has two cutouts that remove unnecessary material and weight, making it lighter despite being half an inch taller. It also includes a new feature called the Spreader-Bolt, which can be used to open the clamp for easy installation and removal without the need for the “penny trick.” The SCS logo is placed in the center of a crown of thorns representing enlightenment and salvation from the past, symbolizing the Sentinel’s role in guarding the future of scooter design. This product was designed and manufactured by riders in San Diego, California, where PROTO is known for its innovative approach to product development and design.
