Lucky completely redesigned the Lucky SCS compression system; stylish and strong are two words that have been used to describe the new shape. The Lucky SCS is a commonly run compression system in the scooter community. The SCS is a one piece clamp/compression system. Once installed and tightened properly the SCS provides great headset holding power and will prevent bar misalignment, even in the most extreme riding conditions. Now available in new brighter, bolder colors. You know you want one. The Lucky SCS is a SCS compression system. The Lucky SCS clamp is a full size SCS because it is slightly larger than a baby SCS but provides maximum clamping power. The Lucky 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 Lucky SCS clamp includes a shim and works with both oversized and standard outer diameter Pro Scooter Bars without a slit. The Lucky 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.
