I was talked out of buying a Steamroller a while back, and bought a Bareknuckle instead. I love the BK, its fast and light, but ended up buying a Mark V Pro to build as a semi beater bike. I really want to compare my IRO with a Steamroller complete to get a better idea of the differences. Im sure the IRO will be heavier than my BK, Phils and all, but the paint job is much nicer on the IRO, that is one thing for sure.
