So it seems that most people on this forum recommend IRO over a lot of other fixed gear options. I'm wondering how the Surly Steamroller compares. It costs more than the IRO and usually costs more means better but not always. I'm looking for a decent FG that is comfortable and would be used to supplement my riding a multi-gear bike. Would either of these frames be a good choice? Oh and I have a Dura-Ace road crank and bottom bracket and Dura-Ace brakeset. Can I use these for a fixed gear bike?
