53cm IRO Mark V Pro

This is the third IRO I have built and I am always pleased with the results.  These bikes are perfect for urban environments like NYC, which is no surprise since IRO got their start as an New York-based company.  This frame is a IRO Mark V Pro in black that I have re-painted, overhauled, and built up with a mix of new and used parts:

  • Miche Pr1mato hubs laced to Mavic clinchers
  • new Continental road tires 700×19
  • Riser bars with Oury grips
  • new front brake, Cane Creek cross lever
  • new Origin8 track chainring, 48 tooth
  • new Origin8 bottom bracket
  • 48 x16 gearing, perfect for the streets of NYC
  • Shimano 600  tri-color crankset, 175mm
  • KKT track pedals
  • new KMC track chain
  • Size 53cm: seat tube center-center 49cm, top tube ctc 54cm, 30 inch stand-over.

    why 700×19 looks like it could fit 28s. Also no foot retention?

  2. naptrax says:

    No foot retention because I prefer to let the buyer get the size clips that fit them. people’s shoe sizes differ too much.

    Great build !
    I have a question.
    IRO Mark V PRO comes with threadless fork.
    How comes that on the picture there is threaded fork and quil stem ?

  6. naptrax says:

    The IRO Mark V originally came with a threaded fork. It was changed to threadless later. This was one of the earliest ones, which I think had better tubing and design.

  7. Unquestionably imagine that which you stated. Your favorite reason seemed to be on the web the easiest thing to
    keep in mind of. I say to you, I certainly get irked whilst other people consider concerns that they plainly don’t know about.
    You controlled to hit the nail upon the highest and also outlined out the entire thing without
    having side-effects , folks can take a signal. Will likely be back to get more.
