1980's Peugeot Mountain Bike Tange tubing question.
I have a Peugeot Mountain Bike with this sticker:
https://www.velocals.com/media/01/a20...6ffcb83f_m.jpg
It also has a green Mangaloy 2001 tange sticker on the fork.
How does this frame/tubing compare with my PX-10 Reynolds 531?
Thanks...

No comparison. Two comletely different tubes for 2 different purposes.
Reynolds 531 variants and Columbus SL/P/X were the industry standard through the mid-80's when 531 fell off the map. Columbus is cromoly 531 is not. Tange made good tubing but the stuff your referring to is run of the mill cromoly.

Mangaloy was a manganese- molybdenum alloy like Reynolds 531, but unlike the seamless, butted 531 tubing on your PX-10, Mangaloy is a seamed, straight-gauge tube.

Thanks guys,
How does straight gauge chro-moly compare to hit-ten or carbolite?
I like this bike for snow/ice/rain commuting, it seems to be heavy duty and gives me a solid ride in inclement weather and it inspires confidence for some of the crazy frozen ruts etc.
I don't think my Reynolds 531 PX-10 would be as durable, horses for courses as it were...lol
I was just wondering where it sits in the bike frame hierarchy of bike tubing.

Mangaloy was available butted. It's closest cousin is Reynolds 501. Not drawn tubing like SL or 531. The 80's were the dawn of new welding technology which resulted in tubing that was significantly better than what had been available historically. All True Temper tubing is seamed, but you could hardly tell with the AT/ATX stuff that came out in the late 80's/early 90's. I would suspect, but do not know, that Tange would be farther ahead on the tech curve than Reynolds of the early to mid 80's in this regard.
Early production MTB's suffered from both a lack of design history as well as a lack of widely available tubes specifically design for off road use. Lugs were not available for the over-sized sets, and oftentimes the angles were outside what was being built. A lot of the respected tube sets from the road scene broke due to poor fabrication, or the fames could not handle the abuse. Further, what was available became suddenly hard to get by 1984/85 as all the major bike companies dived into MTB's in a big way. At the end of the day, it is a middle of the line tube set. However, production bikes of this time frame, and often the highly sought customs, all used these sorts of tubes. Frankly, any pre-1986 MTB frame that is butted rather than straight-gage is pretty good relative to what was available at the time IMHO.
