Just brought this home tonight. I believe fork, 700C rims w/ s.s. spokes and brakes are likely not original, not sure about the rest. I'm guessing someone spent some time putting this together as a close-to-stock bike. Campy almost everything. Cinelli stem, Mafac brakes.
Any thoughts/comments welcome. Guessing early-mid 70's but I don't really know. I haven't ridden a bike for probably 15 years
I had my brother's Grand Record while he was in the Peace Corps (Lesotho) in the late 70's. He came back and stayed with us in Berkeley while he got it in shape and then rode it up the coast into Canada, across and down to my other brother's in Long Island. Came across this bike yesterday on CL and felt like it might oughta be mine and so it is.

Mark, based on the serial number it should be a 1975 but to me it looks more like a 1974, unless the camera exposure has affected the lighting. This looks pure silver, as opposed to the silver lilac used in 1975 (see post #2 of this thread for a 1975 Le Champion).

My brother's Grand Record was a warmer silver than this. You're right this is a very neutral pure silver color.
Thanks

Both had some parts swapped-out.
Super Mirage

Based on catalog reviews, it looks like a 1978 or 1979

Grand Touring

Here is my contribution. I guess mid '70s but someone here likely knows better. Serial number is on the left dropout: 2751232. Photos on my Google+

I have a Grand Record frame that I got with some parts I assume were original. It came to me with headset, stem, bars, bottom bracket, seat post, and saddle, but that's it. I'm fairly certain it's a 72 or 73 based on what I can glean from catalogs and pics of other bikes on the web.
- Reynolds 531 main tubes
- Maes bend bars (I'm assuming, since no markings)
- No chrome "socks" on the fork
It's not critical that I age this bike, since I am taking some liberties with the build (Suntour drivetrain, Stronglight 93 crank), but I just bought a backup set of Campy NR drivetrain parts from a 72 Mondia in case I ever want to restore it. It'd be nice to know if the Campy parts are the right year, just for my own edification.
Left dropout has the number "1263931"
Right dropout has the number "4216"
Here are some pics -- ignore the placeholder wheels from my old UO-8...

Bikes: 1974 Motobecane Grand Record
I have a Motobecane grand record that I purchased new in 1975. It is a 1974 model, serial number 2462490. Everything is original except the seat post , which I added, tires and the handlebar wrap.

Great looking bike, hillcountry! How many bikes from that era are still with their original owners, in such good condition?!
What's the dealer sticker down on the seat tube?

Thanks Al! The dealer sticker is from the old Turin Bicycle Co-Op that was on the near North Side, Rush Street perhaps. I remember leaving the store when a fire truck, a hook and ladder came honking down the street, klaxon blaring and a dalmatian was on top, going to the fire with the firemen. Really neat!

OK people, I've only got another 500 posts remaining , so I've decided to make an attempt at decrypting one last serial number format. It seems Motobecane's format has been giving people fits, so I'm willing to give it a shot, if you want to play along.
Most of you already know the drill. Post pictures of your Motobecane (full drive side and detail pictures of major components, tubing decal, headbadge and serial numbers). Provide as much info as possible on the components including brand, model and date codes (when available). Refer to the components page of the Vintage-Trek website if you need a primer on component date codes. Bonus points if you already know the year.
NOTE: Motobecane often have several sets of numbers on the bottom bracket shell. I need ALL of them, as we don't which which holds the key to dating.
I'll be tabulating and analyzing the data. A summary of the findings will be posted here (i.e. post #1). Hopefully, it will as successful as the other, similar threads (Bianchi, Centurion, Fuji, Miyata, Nishiki, etc.). TIA.

Got a Motobecane Mirage Sport, 1983 possibly. BB has a serial number M68**507v. Two numbers are under the cable guide, which has text modelle vitus depose. It means something like model vitus registered. The plate has no screws or anything, so I don't know if it can be taken off. M stands for Moto, I believe, but small v, if that has any meaning?

I picked this one up today. It was advertised as a 1972 Grand Record, and that seems to be consistent with the information in this thread.


The serial number on the outside of the left dropout is 1238406.

Assuming sequential numbering, that would place it somewhere just ahead of the yellow 1972 Grand Record shared by [MENTION=158148]VonCarlos[/MENTION] in post 32 (s/n 1250892). Mine has the same paint scheme as the GR shared by [MENTION=41131]noobinsf[/MENTION] in post 59 (s/n 1263931).
I would also note that though noobinsf believed his to be a '72 he has a different Reynolds decal than VonCarlos. The latest H Lloyd Cycles timeline says this decal change happened in 1973, though there obviously could have been a transitional period.
The number stamped on the inside of my right dropout is 64216.

I would note that this is the exact same number stamped in the same location on noobinsf's Grand Record and the Grand Record shared by [MENTION=243294]acoffin[/MENTION] in post 18 (s/n 1428239) which also has the same color scheme as mine, so that number must have something to do with the manufacturing process and not the specific frame.
The bike shared by acoffin has a different head badge, and it has Weinmann brakes, which according to the catalog scans at bulgier.net would likely place it as a 1973 or 1974 (the scans list Universal brakes for 1970-1972).

Here's my recent pick up. No serial number that I see, the only number on the bike is the 60 on the back of the fork. Components include Weinmann symmetric brakes with 733 on the back, pivo stem and bars, Huret Svelto rear derailleur.

You know how sometimes you just post at the end of a thread and then read backwards? That's what I did. Here's the three numbers on the rear dropout. The one on the outside is hard to read xx45554 the others are matching 65116.

I have (well, really, my wife has) a nice Motobecane Grand Touring mixte. I spent a bit of time trying to figure out the serial number. Unfortunately, just about the only visible spot of rust is the serial number under the bottom bracket shell. After some vinegar soaking and a bit of work with bronze wool, I think I might be 1226618. I'm not 100% sure, however.

I'll be very grateful for any clear insights about the year of this recently acquired Grand Record. I'm placing it between 1974-77 but would love to narrow that down.
The bike is known to have belonged to a collector but came to me with no details about it's history. It appears to retain many original parts but also some others that together don't match any catalogs I've found. Appears to be original paint. It has unusual road/race gearing (52/45 -- 14-21) with period correct components. Can't help wondering if it might be a bike that was caught up in the component supply shortages of the early seventies and assembled a bit off-catalog. (Ignore the modern saddle and pedals)
For dating note the riveted round head tube badge (for the GR... 1973-??), lack of brased on cable guides (pre-77...?), Campy rear drop-outs and remnants of a Reynolds 531 decal on the seat tube but not on the fork.

The 82216 stamped on the right rear drop out seems to me to be some sort of manufacturing code. Note that almost all of the bike in this thread with a number in that location end in '16' with the lone exception being the mixte that ends in '17.'
There really should be a seven digit number stamped either on your left rear dropout or your bottom bracket. These can be really hard to see.
I'm not sure what to make of your component mix. Being a Grand Record, it should have Nuovo Record derailleurs. So I don't think the particular components tell you anything at all.
