ICS 10 compression is a concept that Ethic introduced many years ago and it expanded upon the most basic of compression systems, ICS compression, which utilizes a compression bolt that screws up through your scooter forks into a star nut inside your scooter bars.  ICS 10 took the puny ICS compression bolt and star nut and beefed them up to withstand some serious abuse.   While their are more effective compression systems on the market, it was an interesting idea and is fairly effective but becoming an obsolete compression system as the scooter world advances its technology.
