You cannot just put HIC Bars on normal threadless forks. The inner diameter will be too big and loose to fit around the forks. That's why they require a shim. You can use a pro model clamp on oversized bars, but you'll have to stretch it.
Just a tip, on your website, try and make some of those pictures not give people headaches. Other than that, can't wait to see what you guys come out with.
