Has anyone used one of IRO's Fixed Gear Build Kits?
I'm debating between converting a bike or just buying a Mark V from IRO outright. With the upgraded rims and a front brake the Mark V will be 710.00, which makes me want to cry. If I had more money I wouldn't blink an eye, and I've heard it's a really great bike.

Anyhow, the build kits. So I would buy a frame, and I would probably get the version 3 build kit (249.99) and the IRO Velocity deep V wheel set (249.99). But what sucks is that that's already what a pista or standard mark v would cost. And plus this would be the first bike I convert, and I'm new to all things bikes. (I mean come on, I've been riding a unicyle for the last 3 years).

So deliberate, I'd like to hear if anyone has used these, and if they're worth it.
