Latest build: 1972 Jeunet 630 porteur conversion (pic intensive!)
A few months ago I bought a Jeunet road bike that I found on Craigslist. I was attracted to it because I never had a French bike, because it was my size, and because it had a full reynolds 531 frameset (the 630 was third from the top, roughly equivalent to a raleigh competition). I wasn't sure I would keep it original. The original paint was "French blue" with black lugs, pretty and characteristically French, but there were areas where the finish was really rough, and the lugwork itself was hideously sloppy. I decided to partially correct it by doing some lug profiling myself with a rotary tool, followed by powder coating. I already have another "French blue" bike, so I wanted to go with a different color, but still retain the French flavor. I really wanted to do a full porteur/650B conversion since the frame has fairly relaxed angles and a decent amount of fork rake, but being a road bike, there wasn't adequate clearance for tires wider than 30mm, with fenders. So, I ended up sticking with 700C wheels and did a "partial" porteur conversion: I added a porteur rack and bars, both from Velo-Orange, and I converted it from a ten-speed to a five-speed, with the possibility of adding a chainguard or even a full porteur chaincase (I have the VO porteur chaincase powdercoated in the same color as the bike, but I can't bear hiding that TA chainring!). Total weight as shown is 26.5 lb.
The bike still needs some tweaking, like getting the fenderlines more consistent and a few other minor tweaks. This is going to be my daily commuter.
here are some pics, and the full flickr set can be seen here.

What kind of handlebars and brake levers are those? Where did you purchase them?
That is really a beautiful result.

I've got to say that I like the original more, the picture of the original makes it look quite nice.
I'll trust you, though, and assume that the paint was terrible and so were the lugs.
I have a 5-speed single-in-front setup, and I find the chain drops of the front ring all the time. Do you have the problemo?

thanks all for the comments!
brake levers are tektro inverse brake levers, handlebars are velo-orange "porteur" bars. i purchased the bars and levers from velo-orange.
well at least it's not an ava stem! and if the great constructeurs did this, it's good enough for me! besides, how many stems crack in the middle of the neck? i would imagine most fail at stress points like the bend, or the clamp?
it's hand-cut and filed from a piece of aluminum tubing. it was a kind gift from 3rrr products. he's a sculptor by training and trade.
i haven't had any chain drop yet, although it's been ridden less than 30 miles (i finished it the day before yesterday). however, i do have a chainline problem, in that the largest cog is way too afar off chainline that the chain clatters badly on the jockey wheels. ideally i need a bottom bracket that's 5mm narrower on the drive side, but good luck finding one! (french threading, and all).
i can understand how some people prefer original paint schemes. if the bike came from some special provenance, i probably would have kept it more original.
here's a before and after of the seat cluster:

Your conversion is simply gorgeous! Before I saw this bicycle, I had been contemplating putting those VO porteur bars and inverse levers on my mixte, and wrapping the majority of the bars as you did, so I could grip them at various places. Are you finding this set up comfortable? Also, I am curious where you plan to put your lights as this your daily commuter. will you do a rack and fender mount?

yep, i plan to do rack and fender mounting of the lights. i plan to mount one or two headlights underneath the rack. i should still be able to use front panniers with the lights. i will likely do an LED retrofit of some NOS cibie headlights i scored off of the 'bay:

for a taillight, i picked up a NOS soubitez fender-mounted light unit, missing the incandescent internals. i finished the LED conversion, and it'll be ready to mount once i fabricate an internal mounting bracket for it:


i documented the LED retrofit on my blog, for anyone interested.

Very nice, Make me think I should rethink getting ride of my 75, same size and all. But my 1975 has a few annoying features and one is the infamous 1970s short reach front brake and long reach rear. It does not appear yours suffers from the same affliction! The only nice thing on mine is the chrome, very good quality, the rest of it is horrendous. I also had to straighten both the frame and the fork on mine thought I road it no hands just fine before I ever had the fork straightened. someone also did a horrendous job of tapping the BB to italian so it carries a lot of baggage but has served me well as my daily ride fixed gear for over 3 years.
