Okay I deleted all the posts because most of the people had no idea what they were saying.
You need to put a slit in your bars so your clamp can compress them against the forks. You do not need ICS, HIC or SCS, those are for threadless forks. So basically get a better clamp (Half Knuckle or SZ clamp) and cut a slit. I would not recommend district clamps, they strip very easily.
