IRO are made in the same factory as Surly with 4130 steel just like Surly.
Seems like Surly just charges a little more.
I have a Mark V frame set and it performs great. The fork is a little heavy.
But for $50 on ebay you can get a nicer steel fork. Personally, I ride the
fork that came with it and have had a lot of fun.
