SCS is simply the most effective compression system around and the new Trynyty Simple SCS is no different. Compressing your forks and bars without a slit independently, there simply isn't a stronger compression system around. The Simple SCS includes a shim so it works with either oversized or standard bars. Available in 5 color ways, there's a color that should match just about any pro scooter out there. The Trynyty Simple SCS is a SCS compression system. The Trynyty SCS clamp is a full size SCS because it is slightly larger than a baby SCS but provides maximum clamping power. The Trynyty Simple SCS only works with SCS bars without a slit. 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 Trynyty SCS clamp includes a shim and works with both oversized and standard outer diameter PRO SCOOTER BARS without a slit. The Trynyty 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 Trynyty Simple SCS works with the SCS compression ONLY.
