Grand Jubilé, modern constructeur edition

It looks like this is a day for Motobecane Grand Jubilé threads.

I had another thread for this bike showing the progress as it developed, but now that it's finished I wanted to start a new thread to show it off.

This is a circa 1975 Motobecane Grand Jubilé that has gotten the full 650B makeover treatment and custom rack at the hands of our resident torch master and a nice powder coating, decal, and lug lining from Groody Bros.

How is BB height with the 650b? When I rode down to the end of the block, I thought it felt low enough with 27s.

I like it.
curved Seat stay bridge, nice detail to secure front fender.
re-raked fork, original chrome?
and nicely detailed powdercoat job. ( i actually stated that.)

Nice, but how did you deal with the Huret, Campy dropout issue?

Edit to add,

I was going nuts looking at your photos and comparing them to my GJ.
Mind doesn't have all the bosses installed.
Then I looked at your other thread.

Now I'm assuming you welded on a seven o'clock stop on the dropout?

It came with Campy dropouts.

Then it's a '76.
Only 1976 came with both Nervex lugs and Campy/Suntour dropouts.
The best year in my opinion.

Edit to add.

Crap, I made a mistake.
1976 and 1977 came with both the Nervex lugs and Campy/Suntour dropouts.

As the OP stated, it came with Campy 1010 dropouts. But modifying a Huret 4 o'clock to Campy 7 o'clock position is easy to do with a bit of square brass stock, a torch, and some silver filler...



Braze, deflux, hacksaw and file...

Looks great. The rack is awesome and the paint is really really good.

Shimano really nailed it with those CX70 cantis. Not the prettiest brakes but they work super well.

I haven’t had any problems, and I’ve put about 500 miles on this bike in 650B mode, including a good bit of gravel. I’ve actually never ridden it with anything other than 650B wheels so I can’t say what effect if might have on the handling, though that’s been good the way it is. I just measured the bottom bracket height at about 260mm.

I'm glad someone noticed that water bottles. I put those on just for the pictures.

I just have to ask - what is going on with the saddle position?

It's like Italian driving,
short legs and long arms.

Beautiful bike Andy, lots of fun little details in there.

I noticed you have a holder for a front light but what about the rear?

I'm still figuring that out. I usually use Specialized Phenom saddles and I have the bar to saddle distance dialed in for those. I used that as a starting point for this one and figured I'd adjust it to feel from there. It's actually pretty comfortable, but I think I can bring it forward a bit. I also think I need a seatpost with more setback because @gugie was riding behind me today and said he could see the saddle flexing. That's never a good thing.

I'm an battery-powered LED light kind of guy, and the rear light I use most often wraps around the seatpost.

What? This old thing? It's hardly worthy of a hook in my garage.



I'm cornering the market on pimped out, powder coated Motobecanes.

Have you considered raising it instead of moving it way back?
