Photobucket ate my previous photos, so . . .

Photobucket ate my previous photos, so here are some nice pictures of one example of Koichi Yamaguchi's work that I consider myself lucky to ride.

Please provide more details on this lovely creature. That seattube situation is stunning. All the lines on this bike catch me off guard in all the right ways.

I saw this thread when it got linked yesterday--I still have my fillet brazed Simonetti--by Mike Howard. This was my 'Great Recession' bike--sold the nice stuff and picked this up. I found it interesting that by this point ('90s) this frame still feels 'Italian'--not dissimilar from the Masis of yore (except for the CF fork)...Sorry no close up shots of the fillets.

So this is what in France is called a bi-tube.

The concept is far from new and you can find lots of examples from different countries going back to the earliest days of cycling.

But they came back into fashion for a while (back in the late-80s early 90s) among frame builders here (Mecacycle, C.A.C.E.G etc) in search of stiffer frames given the materials at hand.

What that meant was developing shorter stiffer rear ends and finding a way of keeping the seat-tube out the way - resuling in either bi-tube or curved (see Ganolo/Cycles Laurent, Didier Louis) seat-tubes.

This frame is from Paris-Tours*, a framebuilder situated in the Montreuil area on the eastern edge of Paris. Around this time there were quite a few framebuilders in this industrial/artisan quarter, inc. Alain Michel, C.A.C.E.G, Polchlopek, Didier Louis, Bernard Carré). This bi-tube was one of their models at the time (along with more standard racing and touring frames) and they often had a variation of this complex layered spray-painted design (I believe this is their 'Bahamas' design).

It actually has oversized tubing too which was quite new back then (and puts in towards the end of this bi-tube era).

It was painted by Broggio who was the premier painter at the time in the Ile de France area and you'll find lots of high end frames with the 'Email Broggio' label on them well into the 90s.

* It may have come through the Cycles Gillen shop. This shop was on the edge of Vincennes/Montreuil and they sold their own frames (including bi-tubes, at one point frames built in house, supposedly some generic C.B.T Italia frames too, and likely others from Montreuil builders).

There is always dekerf. Love the seat cluster on my bike, here are a few other examples

https://dekerf.com/special-projects/...d-gravel-bike/
https://www.dekerf.com/products/fram...h-custom-stem/
https://dekerf.com/products/complete-bikes/road-bike/

My next bike will be a fillet brazed kirk with gothic lugs. Won't happen for at least 5 years, hopefully Dave is still building then.

Thanks for the info and history on the frames and builders in that area - I'll do some more research.

It's such a beautiful frame, the paint very striking. Honestly, these days, stories and history like this is what keeps me interested in bikes - I hardly ride them.

Fortunately for me...my lower back/glutes/hamstings are still quite flexible.
