Lol Keon5 are you kidding me? If people made longer forktubes and shims for HIC less parts would break. The stress at the slit is almost entirely removed if the forktube goes another inch or an inch and a half above the slit. I've had my bars and forks for over a year now and not a damn thing has happened to them since (aside from me repainting them a few times.)
SCS works fine, looks ugly as sin, weighs more than HIC and makes bars only SCS compatible (unless you put a forktube in the bars).
HIC works nice, scooters look better, its cheaper, when done correctly it's more reliable, when done like I've done it it's pretty much indestructible.
