Hmm, the headset - it's been so long since I put it in that I can't remember for sure! I know my older Yeti is a 1 incher so I stuck a BMX one in there!
Elev12k - thanks for the tip on Commandant. I haven't seen it in the UK but a classic car enthusiast friend swears by Autoglym so I might give that a try.
I lived in the US for a short time ('92/ '93) and from memory reading an ad for Yeti, the Pro FRO was only meant to be sold to NORBA members. Not to sure how they were to do this - maybe you had to give your licence number when ordering?
Different angles and different materials. The Fro had 4130 steel, the Pro had Tange tubing.
This one looks more like an regular FRO. The seat binder is def a FRO style (BMX style). The Pro has just a bolt. Allso the cablestops are welded, the Pro has aluminium stop blocks that are riveted to the frame.
