- 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 SCS is a SCS compression system. The Proto SCS clamp 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 Proto SCS clamp 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 SCS works with the SCS compression ONLY.

Scooter compression is the single most important concept to understand when building a scooter. Your compression system drives which parts you will need to purchase in order to complete your scooter. Contrary to popular belief, not all scooter parts are compatible with each other. In fact, most of them are not.
SCS COMPRESSION
SCS compression is the most effective compression on the market. The downsides are cost and weight but, if you want to keep your scooter dialed without ever having to tighten your clamp, SCS is the way to go. When running SCS compression, you will need bars without a slit. Most SCS’s come with a shim so they will work with either diameter. However, if your SCS doesn’t come with a shim, ensure that the diameter of the SCS works with the diameter of your bars. SCS compression will also require the use of SCS forks.
HIC COMPRESSION
HIC compression is a popular option among pro riders. While it is not quite as effective as SCS, it costs a lot less and is a popular option for those riders who want the lightest setup. If you are running HIC compression, you will need an HIC kit, oversized bars without a slit, and an oversized double clamp (or a clamp with a shim).
IHC COMPRESSION
IHC compression has become one of the more popular types of compression, as the compression system is built directly into the forks. That means that you just need compatible bars and clamp. Pick up a clamp with a shim, which will work with either oversized or standard bars. You can run either oversized or standard diameter bars with IHC forks as long as they have a slit. But the steel bars need to have an oversized inner and outer diameter. Aluminum bars just need to have a slit .
