I answered a craigslist ad and came home with 3 neglected bikes for $75. Couldn't go wrong even for parts. Trek serial number M3B7B85 seems to place it as an 82. Looks like it wouldn't take much to make it rideable. Fork crown is pictured as in my research I saw lots of posts about forks failing in this generation. I already have a higher quality 83 Trek 700, but the price was right.





neglected and dirty and stem above minimum








Another bike was a Motobecane Grand Mirage missing the wheels, but otherwise complete including a nice Suntour V GT rear derailleur. That one is a bit beat up.

And last is a Peugeot. I always knew I would come into something French sometime. There are some numbers under the cable guide under the bottom bracket, but I only saw a 37 as the first characters. Lots of French knowledge needed here as I searched some catalogs a bit and didn't see a match.


I was thinking early 80s ??






Nothing fancy



I thought these were from the 70s



Stronglight 99 maybe



Replacement rear wheel


Actually, I don't think this one is too far from rideable either. The rear wheel has been replaced because of damage. Included is the Mallard heliomatic 6 speed rear with a couple bent spokes that ripped a couple holes out of the hub. Front hub is Mallard too and rims are the Weinmann concave.. Pedals are Lyotard quills that say 9/16x20. Seatpost is 25.8mm. This bike actually felt lighter than the Trek. All 3 bikes are 27".

I am retiring in less than a year so maybe these are projects then. The Trek is easy enough to figure out, but I was curious about the model and desirability of the Peugeot. I can't go wrong for the price either way.

That’s a UO 14 and in some ways the best of the UO series as it is made of nicer tubing. Yes that's a stronglight 99 crank. I like 86 bcd cranks a lot since you can run them as compact cranks.

I picked up an '82 Trek 412 a few years back for $50. I took it home, read about the fork crown, stripped the bike for parts, and hung the frame up.

Thanks for that info. What year might it be? Am I to assume with the more common pedal threading that it may also have some other more “standard” parts?

Early 80s ('83 I believe is when it came out). I don't remember offhand about the threading but by '83 yeah I think the threading should be standard for the pedals and the crank will take a standard puller.

Thanks again. That narrowed it down, and searching revealed 83 after your clue . A bit of searching showed these may have been built in Canada. Either way, by 83 one may not have to fight too much French quirkiness. Good for a first French bike to learn on seems.

And yes, I did see the Trek fork comments while researching. Interestingly pics of failures didn’t show the fork crowns with the Trek stamping. I also read one post that said Trek switched to Tange forks late in the model year. Jury is still out on this one too. Hopefully more comments coming on that bike also.
