Eight years after inventing the world's first and best Standard Compression System (SCS), PROTO is proud to introduce the next generation of SCS. The Sentinel SCS is the most technically advanced Standard Compression System ever created. Coming in at 3.5", it offers a full 2 inches of handlebar support to accommodate the taller bars we are seeing become more prominent which is over 30 percent more support than a 3 inch SCS. It also features larger 8mm bolts with 6mm allen drives and an offset slot providing 25 percent more threads for the new larger hardware to tighten into allowing for increased torque and decreased chance of stripping giving it the ability to stay tighter, longer than any other SCS on the market. To top it off, despite being half an inch taller, increased weight was not an issue with its tapered top and base and two cutouts that removed 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 the penny trick. The SCS logo is placed symbolically as the third eye of the Sentinel 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. The Proto Sentinel is a SCS compression system. The Sentinel SCS is considered a baby scs because it only works with standard SCS bars without a slit. A baby SCS is slightly smaller than a full-sized SCS but provides equal clamping power. While SCS compression is more expensive than other compression systems, it is the most effective compression system you can put on a pro scooter. The Sentinel SCS was designed to work with standard outer diameter bars without a slit and cannot be modified to work with oversized bars. The Proto Sentinel SCS includes M8 bolts for maximum clamping power. M8 bolts are much less likely to strip than M6 bolts. It is a good practice with any compression bolt to tighten each bolt 1/2 turn at a time, one bolt at a time, until all bolts are completely tight. The Proto Sentinel works with the SCS compression ONLY.
