ID a Motobecane, BB 35 x 1?

A crappy pic I know, but can anyone help with an ID? or even better the vintage?


I might buy this frame, but it doesn't have a BB. Any idea if this frame has one of the 35 x 1 BBs that has a tendency to "unthread" itself?

I did a fair amount of googling and searching this forum, but I couldn't match the small type on the top tube to match any pics I found.

Thanks!

35 x 1 can indicate eithor French (both sides right hand thread) or Swiss (left side left hand thread). French is the one somewhat prone to auto extract (along with Itialian), Swiss is technically superior but even more of a hassle/expensive to source replacement parts. Motobecane aparenly used both french and swiss at various times, you would probably need to look carefully at the left side threads to determine what it actually is, or try to thread in a know french or swiss BB.

I can't ID that without a better picture.

You can get a threadless BB. It won't slip out.

Thanks for both responses. I was aware of the difference in the Swiss/French threads, but come across the threadless BB option.

I'm checking out the frame in person tonight.

Based on the length of the type on the TT, I can only guess it's a Sprint. I'll know soon enough.

It's a Le Champion, in very good condition. It came with the Campy stem and 3TTT bars. I haven't confirmed it myself but the guy I bought it from said it's the French thread.

Just look closely at the drive side threads. It's not hard to tell if they're left or right threaded. Unscrewing will not be a problem if you torque the right cup properly and maybe use some blue Loctite.

There are no cups... but I can figure it out by running my fingernail along the thread.

Yep. 531.

and I think I got it for a reasonable price: $60

If I didn't I don't want to know

I wasn't telling you to look at the cups. I was telling you to look at the BB threads. No fingernail is needed. Just eyeball it.

No harm in using a fingernail. I'd trust that better than my eyes.

$60 is a very good price. You will enjoy it. Do you have the rest of the bike ready to go on it?

Ah, of course... I should employ my grade-school comprehension skills next time

Not all the parts, just found that two days ago on CL. I hate to admit it here, but it will not be a restoration project (at least not for it's first re-incarnation).
My wife wants a FG and I've got some parts (obv. need a BB, and I need some wheels). I won't modify the frame at all, so it could be restored at a later date.

I'll take some pics in the coming days before I start the build.

I haven't confirmed it by measuring, but the guy who sold it to me said it was a 52.

As promised, better photos attached.

Also, I've confirmed that it's French Thread. I haven't been able to track down the year, but if I had to guess, it would be late 70s/early 80s.

The rear spacing is 120 and the fork spacing looks to be 96mm. Should work nicely as a fixed gear.

Don't go nuts over the fact that it's French thread. Just make sure you tighten down the cup when you install it - use Loctite if you wish.

There are half a million fellows on this forum with Italian machines that they ride hard - it's been quite a while since I've seen them complain about a loose cup. Loosening drive-side cups are from an age when not everyone knew to use threadlock or to tighten them quite tight to prevent them from spinning out.

The advent of the internet, and good ol' Sheldon filled everybody with enough loose-drive-side-cup-fear that you're not going to see it happen - if you follow his advice.

Thanks! I've read enough now about dealing with French threads that I'm not too worried. If I can't a BB at the LBS, I'll get one from velo-orange.

I'd still love to narrow down the vintage.

Is there a Motobecane serial number database anywhere on the web?

don't know about serial number DB, but there are several catalogs you can view on Velobase
https://www.velobase.com/Resource_Too...alogScans.aspx
based on the head badge and graphics, plus the portacatena DO, I'd say the OP's is around '78 (give or take a little).
It would make as fine a multi-geared bike as a fixie...no, it would be finer.
