Nah guys, i think you're mistaking something.
The Helmeri fork has the topcap built-in into the shim/adapter.

If he's missing that, there's no way he can put standard sized bars on an iHIC fork, it would be like putting an oversized HIC handlebar on top of your standard 1 1/8" forktube without an HIC adapter, haha.
How long have you tried to contact the shop? Because you know, it's the weekend, they might not respond until Monday/Tuesday, haha.
A pipe from the hardware store... might work. Depending on what's the OD of the forktube, because I have no idea what's the outer diameter of these when it comes to iHIC forks. But it has to be really snug and fit, otherwise you might end up destroying your handlebars and clamps, yet alone the compression itself. It might be really tricky to find any tubing that has american measurements like 1 1/8" OD... tubes in europe usually dont come in 28.575mm OD's, they either are have like 25mm, 28mm, 30mm OD, haha, full numbers basicly. Do you have a caliper/calliper(sp?) around your house? If yes, use that to measure the OD of the forktube.[/quote]
Haha that's true but they replied and said that there wasn't supposed to be any top cap with the forks but they might be mistaking it like some people seem to do haha. And thanks man that helps a lot, I might have to look into it if they don't want to send that piece over.
By the way, isn't this a bit weird? The compression ring that came with the forks is a bit different in size than the one that came with the headset so that it can fit the fork but that causes the top cap of the headset to be kind of far away from the rest. This might seem stupid but I've just never had a headset like this.. It says in this vid that it's really important to use the headset ring that came with the forks.
