You may have better luck finding info in a MTB forum or even a road forum as Ionics are all recently produced. A quick web search reveals that these are all hand built in Boulder, CO. This jogged my memory a bit and I'm pretty sure that Ionic is just the name that Dean (the ones that make the titanium bikes) puts on their steel bikes. I'd guess that its pretty nice. And that Breezer dropout looks fine to me. Are you looking to have a custom frame made or are you looking to buy this specific one? I have heard some negative chatter about Dean's customer service & communication although I've heard good things about the bikes.
