What are the angles of the 56 cm Super Cousrse and the 55.5cm Carbolite?

HLE is Mangalloy, similar to Columbus Aelle.

My first "real" bike was a 1982 Carbolite 103 framed Peugeot PH10S and it was an excellent riding bike. I dare say that after upgraded component mods it actually gave my later PSV a good run for the money when it came to fun to ride quality. I never could make my PSV "whoosh" like my PH10 did.
I say don't judge a bike by its cover and before you even give it a try.

With this thread revived yet again here, noticing that I never answered this question late last year.

The Super Course in 23" size has a 71-degree head tube and 73-degree seat tube, same as an early-90's MTB or a cyclocross bike.

The similar-sized U09 Super Sport from 1979 (what I call the 2nd-generation, lugged, Carbolite U08/9/10 frame) has about a 72-degree head tube and 74-degree seat tube, at least trending toward the geometry used on some of the early triathlon bikes. It's sporting in terms of rider position, and with quite-stable steering behavior.

Whiskey Tango, there must be some sort of wake-up call that happens around this time of year. Thread has been necro-posted twice now, and in both cases within a few days of the anniversary of the previous post. Is there a certain flower that blooms around this time each year? The approach of the solstice, maybe?

Hi, these are my two internaly brazed Peugeot, white is Hle, other Carbolite. I really love these two. I bought them in poor condition, but now they are realy beautiful rides.

I refurbished this 1985 PX80 recently. Haven't had a chance to ride it much, yet, but am looking forward to it. Thought the frame was rather nicely put together with details like three sets of water bottle bosses, grease port, etc. Cleaner brazing than I've seen on some other bikes made from 531. From another recent post I learned that in 1986 the PX80 had a 531 main triangle, probably straight gauge, which a post above indicates not all that different. This one came with a Simplex derailleur on a Shimano style drop-out.

iI recently bought one of these and left it at my in-laws so I’d always have an escape...er, I mean ride...when we visited. I’ve left the build alone (earlier owner swapped out wheels for 700’s) but my one issue is that crazy old seat post system—too narrow of a diameter to easily swap out. Otherwise a fantastic ride.

I just restored a PH10 (can't post it yet). It had sat on my local Craigslist for a year as I ignored it (and I assume everyone else did) because of the "lowly" 103 tube spec. I figured it would just be a heavy pig, like most high-tensile bikes. On a whim I bought it, mostly to have something to do, and I'm really glad I did. I am shocked at how nice a ride it is, and I wouldn't hesitate to buy another (kinda eyeballing one right now). It's the best value in a bike I've ever seen.

Yours looks like the equivalent to the earlier(?) UO10 model from around 1979-80.

My Carbolite 1979 U09 Super Sport model rides really well for a $20 thrift store bike, though it did need plenty of clean-up and I did also replace the steel-rim wheelset among many other efforts and upgrades (it's got a 6s freewheel now).
I've actually used this one for training rides with the faster local riders and it's a heavy bike but still feels lively enough for such spirited riding.

I'm far from an expert, but I think the PH1x was substantially different than the UOs, particularly with their internally lugged frames.

Also, a correction: I have a PH19, not a PH10. My confusion. Sorry. As near as I can tell from catalogs, it looks like the PH19 only lasted a year or so in 1982. I suspect it overlapped too much with the less expensive UO. The PH10 was offered longer.

The model year really matters, since the geometry of the UO bikes was radically changed for 1979, with steeper seat tube angle, shallower head tube angle and shorter chainstays.
And the lugless construction came in around the beginning of the 80's, producing lighter frames at every price point where this was applied. A lugless PH501 with Carbolite fork actually weighs nearly the same as a lugged 1979 PX10 Super Competition!

There were 24mm alloy seatposts made by Stronglight and other French makers such as JPR. These still turn up on flea-bay from time to time and are a worthwhile upgrade imo.

I think my 1970 ish UO-8 has a 72 degree seat tube and head tube - laid back and low trail. There's a lot of for offset but it could just be a symmetrically bent fork. It's been a while since I rode it, but I liked it quite a lot - I bought another frame/fork same size and year. If I've ever talked about "rando cheapo" while awake, this will be it.

So related to the Carbolite 103 story: I think we do not actually know what the alloy is and how the actual steel correlates to commonly known metals, and I think the same is true for the "allege" used in the UO-8s. But at the time Peug had a gigantic factory in which they could build a bike from rocks to shipping boxes. I understand they made their own steel, drew or otherwise forrmed tubing. That suggests the frame and tubine were designed as a unit, rather than nearly any other which chose from existing tubes to match a bike design specification. Perhaps this closeness of the different levels of design enabled the suppleness some of us have noticed about cheaper Peug frames. It was certainly born of thinner less meaty tubes, but then why were they not widely known for breakage, when not treated as the US precursors to forest racing bikes, or jumped off of garage roofs?

I liked the way it went in a straight line, bent into a turn with reasonable ease, and pedaled easily up and down my local rolling hills. Good basic performance!

Lol! When the Dark Times begin, cyclists naturally think of Peugeot?

I think this was one of their advantages, having the tubing designers, frame designers, bike designers, and the manufacturing process specialists all in one plant/office. I don't know, but if they're all under the same managers and are told "Sit down together and work out a strategy for gradual impovement covering the next 15 product cycles" there could be some amazing improvements. How rigid does it really need to be? Can we double-butt a 1020 tubeset while maintaining adequate strength where it counts? Where on the frame is high-end tubing really needed? Can the most-costly mitering operations be simplified? And, are all these refinements manufacturable? If Frame Assembly needs the Tubing Shop to deliver a butting profile that needs a new machine to be perfected, can that project be prioritized? If Velocio says "I need more flexiness!" how can a big manufacturer provide that for the masses of French cyclists?

Henry Ford brought Ford to the peak of automobile manufacturing on the non-bespoke side by such measures, and when I joined Ford in 1994 those styles of working were still in place.

I don't know if Peug actually did these things, but they did have the chance.

I imagine that Peugeot's frames were quite well-evolved even in the 1950's, but competition and changes in the market eventually find different riders expecting different performance characteristics and using the bikes differently than in the past.

The radical steepening of the PX10's frame angles for 1973 was obviously market-driven in response to more-responsive frames being sold by competitors and being tested by Berard Thevenet and Co.
The UO-series frames were hugely re-designed with new angles, new tubing and all new fittings for 1979, the bikes still had seamed fork legs but the geometry and materials were all new. Cable housing stops were no longer spot-welded to the new lighter tubing and the resulting frames were sportier and lighter (and became lighter yet when lugless construction appeared just a few years later).

So now that I can post links and photos, here's the only reference I can find the PH19 in its short life: https://www.bikeboompeugeot.com/Broch...PH10s_PH19.jpg

And here's a related ad from the same time that highlights some of the upgrades over the UO-series https://www.bikeboompeugeot.com/Broch...20Page%204.jpg

I checked, and mine does appear to weigh in at exactly 27 pounds, as the ad says. Far from a featherweight, but I've seen worse.

And finally, here's my post detailing the rebuild of mine, with lots o' pics https://www.re-cycled.net/posts/dec-...lding-peugeot/
