1974 Motobecane Grand Touring I'm in the process of bringing back to life. My father bought it new in 1974 and it's been hanging in his garage since 1981 without being moved. Lots of sentimental value to this one. Still getting it dialed in and adjusted. Suntour V-GT Luxe derailleurs and DiaCompe SuperCompe brakes. Original Weinmann 27"x1.25 wheels.

My 1980 GITANE "criterium" in original condition, original colour "blue gitane", 12 speeds , HURET "ChallengerII" derailleurs, MAFAC LC brakes, DURIFOR 888 tubes and an interesant SUGINO "super maxy" crankset, with an hollow axle...

The Peugeot PSV-10 in Blue
That was a journey into the computer to get a photo. I remember a guy from work who always said, I’m not as dumb as I look! Anyway, a Craig’s list purchase from NY, well packed, enjoy the ride, it compares well with my Roberts SLX, Mercian 531, and the Torpado SLX

Oi! No drive side pic??! You should at least show off the nice Stronglight 104bis drillium crank, which was the signature feature of the early PSV's!

Sorry, nothing works, went to bikes you’ve had for thirty years and got my Roberts pics w/o problem, beats me!

Some more pics. Really enjoy the shifting of the Simplex derailleurs. Wonder why their reputation is so bad. The headset is Lightrace. The original rear wheel was a helicomatic, with very good bearings and cones, maybe original grease, but a sew up rim, I’ll try to get that respoked sometime. Really nice ride. Couldn’t figure out how to adjust the headset, found an entry in an English classic sight, it’s trial and error, tighten up the lock washer, if it’s too tight loosen, raise the top toothed washer and back off the bottom toothed washer until it’s correct. Brake handles are Spidel, trying some Rustine hoods, but a little small.

The Simplex SX610 that you have there, actually has a very good reputation for reliability and performance. It was the earlier Simplex derailleurs with too much plastic in them that had the bad reputation....consider upgrading your headset to a Stronglight A9 with cartridge or needle bearings. The ones with the needle bearings can last the life of the bike and is super lightweight which goes well with the very light Supervitus frameset. Also consider changing out the shift levers to Simplex Retrofrictions. A very typical upgrade mod on 80's Peugeot that will make the b8ke even more enjoyable to ride.....

What Chombi1 said. Your later version is mostly-metal construction and has the rear slant parallelogram design which improves shifting. I have the older plastic Prestige on my '72 Super Course and the Super Competition on a '72 PX-10 and both shift very nicely, but on the PX-10 one of the rear DR limiter screw mounts has developed a crack. Debating whether to let it go or attempt a repair.

I had one with a small crack in the limiter screw, and was able to fill it in with some superglue. Took a number of applications to build it up to the surface level, but it held up fine. Also, if you lightly coat the surrounding Delrin with the superglue, after a good cleaning, it will give it a glossy black finish that won't fade out like the unfinished Delrin does.

Don't know if I posted pics of this bike yet so here is a 1962 UO8 thai I pulled out of the pile at the bike exchange. That is the original paint!

PilotFishBob 

Right after I posted that I did some searching and found an industrial adhesive and filler set from The Gluesmith. They specify Delrin as compatible, so I ordered it. It uses an activator so it's probably some form of epoxy. Review look good but it's pricey compared to regular superglue. I have a bunch of Prestige RD's I just got from @ryansu so one of those will be my lab rat for testing. I'm a sucker for the things, they do shift nicely while they last - I'll try to maintain them until they finally disintegrate (which they will!).

jj1091

Cool. Let us know how it works out, you could make yourself a full-time job repairing 70's Simplex derailleurs.

jj1091

That's a beauty, love the box-lining details. From back when somebody thought of bikes as a bit of a work of art, not just utility. If you have more pics, I'd love to see more details of the lining.

Not meaning to be disagreeable or anything but that RD really isn't slant parallelogram. The parallelogram is almost horizontal like most slant parallelogram RD's rather than vertical like the Campy NR or Simplex Prestige, but it has no slant. So when the parallelogram swings in and out the lower knuckle doesn't move up and down at all.

Nevertheless, it is a very nice RD. We have a similar one on our tandem and I have one on my PFN-10.

They made at least three variants named 410, 610, and 810, and GT versions. The various models may have had different letter prefixes, but I can't remember which is which. I have to look them up on velobase or disraeligears, and then I promptly forget.

Another one I can't quite remember is that FD which mounts with a screw directly into the ST. I think it is SJA222. My PFN-10 has one like that which I figure I was lucky to have found.

Speaking of similarities, my PFN also has a Stronglight 104 crank for which I found a BIS (drillium) outer ring. The decals are slightly different. I gave mine wheels with Mavic 501 hubs and GP4 sewup rims. The other difference is that my tubing sticker says Vitus 181. It is a very good bike indeed.

PilotFishBob 

Lazy use of the term on my part, actually a drop parallelogram I think. I tend to use the term as a generic for the non-straight parallelogram types without thinking.

here are some more pictures of the 62 Peugeot UO8. I have since put some tan bar tape on it. It will be sold at our spring yard sale. I hope it brings some good money. It should, but probably won't . I am sure that somebody out there would give his eye teeth for such a beautiful bike. Most won't recognize how special it is.

My buddy @gerv is moving out of Des Moines but I did end up with his Mercier 300. He's my bike riding and beer drinking buddy so he will be missed.

The bike as it currently sits is a Gerv special with a stronglight 99 crank, 27 inch wheels with nice Sun CR 18 rims and shimano high flange hubs, shimano L 600 bar end shifters, shimano arabesque FD, shimano light action RD, ideale 39 saddle, dia compe 500g sidepull brakes, and KKT pedals. The headset is the original stronglight P3. I know he got the bike when working at the DM bike collective and my guess is that the parts floated in on different bikes that showed up there as well which explains the eclectic build.

I haven't decided on the build but the simplex drop out has already been modified which means I can run pretty much any RD that I want. Since the bike already has the kinda cool shimano SL 600 bar end shifters, I'll likely go with first gen dura ace RD and a long cage crane RD. The C&V fashion police will likely go a bit nuts if I do that, @juvela are you listening, . I figure with the bar ends, I might as well go with half step gearing (45/40 upfront and 14-34 in the rear) and make this bike eroica capable. Other than that, I'll go Euro with mafac centerpulls (they just look so right on a French bike). I have a set of stout 700c wheels with campy tipo hubs and super champion 58 rims. I likely go with a set of lyotard 460d pedals.

The bike needs a head badge and the reynolds stickers but velocals sells replacements for both:

Build plans sound just fine to me.

If I have been named to the "C&V fashion police" am wondering if such a thing is a promotion or demotion.

Nice that the quatre vingt dix-neuf is a first gen as it lends itself to polishing. Also handy if trebling desired at some point in future.

Me only real question regarding build plans it just how you envision to mount two RD's.

Any readers interested in build plans for a 300 might enjoy following Aurorabucky's wonderful job here:

@bikemig oh oh! Feeling seller's remorse? Nice bike.

bikemig 

Nice build thread; 1 RD works for me, .

Maybe a sachs huret new success RD? Wrong era but they're beautiful, French, and they'll work on the modded drop out.

Sachs-Huret New Success derailleur

CV-6 

This arrived Thursday and I was able to examine it Friday. I am pretty confident the frame is Carré and the fork is definitely Helyett. However this frame does not have some of the features known Carré built Helyetts were know for. Particularly the rear drops and the head tube lugs. Frame takes a 26.0mm seat post and F/F weigh in at a relatively light 6 pounds. So there is a story to be told. Wish I knew it. Braze ons for a pump on the down tube and brake cable stops on the top tube have been removed. Tubing is not seamed, but the head tube is seamed. Steerer is marked with TITAN and 160. So I learned about Titan as a result. Has a cottered RFG BB. I had not seen a RFG BB, plenty of RFG shells, though. No other markings to be found.

Build plans are up in the air. I am tempted to leave it "dans son jus" as the frame is in remarkable shape save for the patina. But Helyett green is so pretty. Link below is detail shots.

My newest bike to my fleet, a 1985 Peugeot P8.
My father found this at a thrift store in Atlanta about two years ago for $20. He knew that I liked Peugeots and brought it up to me. It was in bad shape. The chain was rusted and frozen, the cables and housing falling apart, bottom bracket was horrible, and wheels/tires were in need of replacement. Had it not been a 54cm frame, I would have donated it to my LBS.
So over the winter, I upgraded my other Peugeot, a PGN10, and this P8 become the little brother, getting all the hand-me-downs. I had to do some cold spacing for the wheelset to fit, and since this picture was taken, I've replaced the tires with 38mm Vittoria Hypers and replaced the failing rear derailleur with a Claris 8 speed one.

I'm amazed at just how comfortable how this bike is. Compared to my aluminum Nishiki and the PGN10, this P8 with the carbolite 103 tubing is like a Cadillac. Heavy, but goes over bumps without me even feeling them.

Edit: Bike was a little dirty with this photo was taken. I had just finished a ride with all sorts of dirt and grime over the frame.

bikemig 

These make great rides and take a surprisingly fat tire. Nice job.

noglider 

Sometimes, tires make more of a difference than a frame, though those Carbolite frames are surprisingly pleasing in every way.

obrentharris 

Very nice, Helyett or not! I particularly like the fork tip detail and the fork crown. I note that the earlier dark blue paint is evident on the fork as well as the frame, so if the fork is a replacement, it has been with the frame for a while.

I haven't seen the double pulleys on the bottom bracket before. Are they for a two-cable rear derailleur?
