I am considering getting an IRO.
I was wondering what was the difference between the Mark V and Mark V pro. Is it just one uses Cro-mo tubing and the other uses Renoylds 631? Does that really make a difference??

I've been riding fixed for about a year and half now. I am def. digging it. I am wanting to upgrade from my conversion. I want something that is reliable, that I will admire, and has track geometry. Im deciding between the BD Kilo TT vs IRO. What do you guys think? Which should I go for? Since I am over the whole beginner bike thing, I want a bike that is very nice and will last a long time. Can the IRO do this? And I am prepared to spend $500 toward it.

I am thinking to buy a frameset, transfer my wheels over and invest in a headset and BB and cranks. How much do you think that would all cost? I am a college student so I can't spend too much but I want the components to be reliable.

And is there going to be another IRO group buy coming up soon? Did you guys really get IRO frames for around $150? If so, I am prepared to wait until next summer to get a groupbuy IRO.
