Eight years after inventing the world's first and best Standard Compression System (SCS™), PROTO is proud to present the next generation of SCS™. The Sentinel SCS™ is the most technically advanced Standard™ Compression System ever created. At 3.5 inches tall, it offers full 2 ​​inch bar support to accommodate the taller bars we see becoming more prominent, which is over 30% more support than a 3 inch SCS™ inches. It also features larger 8mm bolts with 6mm Allen discs and an offset slot providing 25% more threads for the new larger hardware to tighten, allowing for increased torque and a decreased chance of stripping, allowing it to stay tighter, longer than any other SCS™ on the market. To top it off, even though it was half an inch taller, the increased weight wasn't an issue with its tapered top and base and dual cutouts that eliminated unnecessary material and weight. There is also a brand new feature called the Spreader-Bolt which can be used opposite of the 4 main clamp bolts to open the clamp for easy installation and removal, totally eliminating the need for penny tricks. The SCS™ logo is symbolically placed as the Sentinel's "third eye" in the center of a crown of thorns representing enlightenment and salvation from the ways of the past and guarding the future of scooter design.
