I just got a new IRO Mark V frame in the mail and am going to transfer parts from my old bike/build onto the new frame. Only problem is that I cannot seem to find any definitive instructions on the net about what to do about attaching my fork to my frame.

The fork came with a very long steerer tube. I know I need to cut that, but don't really know how or how much room to leave when cutting, and I know IRO uses a threadless headset, but do I need to use exactly that, and i really have no idea how to install a headset once i get it.

Is all of this difficult to do? I've got basic tools and am enjoying learning about/working on my current bike. I'd love to avoid having it done at my LBS as I'm a do-it-yourselfer, but hey... I'm also realistic. Est-il possible por moi?

Any instructions, instructional links, and/or confidence builders would be greatly appreciated.
