The Mystery Project Less Mysterious

A mysterious and unique frameset I picked up over a year ago is nearer completion.Photobucket
Photobucket Despite a disastrous "trois-coloures" red-white-blue motif, I saw some potential in this little number. After stripping the paint off, I discovered some serious pitting on the chrome surfaces. The prior finish seemed to have been automotive style, as liberal amounts of bondo were used to deal with the deep pits. I also learned that the fork threads and BB shell were French threaded, and it was built of Vitus tubing. With a country of origin determined, I had a place to begin my research.BB shell Thanks to the help of the internet and all the old bike nerds that are plugged into it, I learned this is an early Mecacycle Turbo, made in St. Eteinne, France. Obviously, one of the most unique features of the frame being the Vitus fork blades incorporated into the "seat-tube" so the wheel can set as far forward as possible. For a 59cm frame, this makes the stays almost comically short. The fork uses the same blades and provides some appealing continuity from front to back.Photobucket After lots of sanding, primer, sanding etc. I got rid of the pits and commenced the final finish work. On a whim I decided on white and OSHA orange. I like an orange bike, but I already had some white striped tires and white bar tape. Photobucket
I managed to tackle the headset problem with a found old (but not worn out) Campy Neuvo Record French threaded top half of a headset, and an old (again not worn out) Shimano 600 bottom. Photobucket The bottom bracket was actually a cinch since I had a set of Phil French rings, and a Phil BB for my Chorus cranks. The inner-chainring even clears the preposterously wide chainstays (made even wider when I changed the spacing to 130mm), but barely. The I.D. of the fork's steer tube is 22.2, weird for a French bike, but a relief for me! Besides, I still need to figure out how to fit a front derailleur on one of the "seat-tube blades". Not to mention finding a longer 26.6 seat-post with an internal wedge...

Vitus fork blades!

I was wondering what the heck was going on with that split seat tube. Wild stuff Billy, keep at it! Love the new paint too.

i bought a mecacyle frame in 1985 or 1986 ...

... still in use, original colors dark blue/light blue, with chrome fork, and chrome rearend

they are wonderful! for their time a bit heavier than others, but strong, and short - very agile but yet stable at high speeds

love it!!!

great find - send me an email if you want some pics!
