Today I picked up this old Trek 420 from a church sale. I did some research before making the trip and realized it was one of their lower-end bikes but I knew I couldn't loose at $20. I believe this to be an '84 model made of Mangalloy steel, not cromo. The interesting parts are the saddle and rear derailleur. At first glance I thought the saddle was a brooks but closer inspection revealed a brand I didn't recognize "Ideale" It's a french saddle and this is the "90" model. The other interesting bit is the rear derailleur. It's a long-cage Suntour Cyclone M II.
I was excited to see Simplex front D, Shifters and Pump mount because I'm restoring an old px-10 and these parts, though not OE for the PX-10, would make for a true-enough restoration.
It would seem the previous owner replaced the mediocre factory parts with parts way above the bike's class. I know there are desirable versions of each of these items but I want to check and see if I have anything special here.
