Why not move the Univega rear wheel over the to the Moto and replace the brake cable and replace the tires. Then you can look around for a donor bike or a great deal on a set of wheels to get the Univega on the road? If the brakes have enough reach you could convert one to 700c.
Has the Moto been a good bike to ride, or has it been lacking for you in any way?
Motobecane Grand Touring were/are very nice bikes - Vitus 888 tubing, good components, but French. The Univega Nouvo's were lower tier, but nice to ride. The Moto was considered the better of these - so I'd keep the Moto and swap parts, as needed like a wheel, from the Univega.
How do you keep an idiot in suspense?
Well, the Nouvotech uses 700c wheels while the Motobecane is the old 27 X 1 1/4 in tires. Is'nt it difficult to swap between the two and also find the right freewheel that matches the gears?
Why is being French a negative quality?
French can be an issue due to odd threading / size of some components that are no longer readily made or available. They are available, but generally at somewhat of a premium compared to similar quality standard stuff.
The brakes should be Weinmann center-pulls. Likely enough room to switch the 27" for 700C's. I really liked those old Weinmann brakes - after I removed the "suicide-levers" from the bars.
How do you keep an idiot in suspense?
I actually have a Weinmann rear wheel (700C x 23) that I tried to fit on the back of the Motobecane but it was too wide. Can I use a 700c wheel? Will it be weird with a 27 1 1/4 in front wheel?
yes it will be weird and we might make fun of you.
Your bikes have different fork spacing for the rear wheel. The Moto is likely 126mm or possibly 120mm and the Univega might be more like 130-135mm. Take a ruler to the rear dropouts and measure.
It seems to be 120mm.
I just want to find out which bike I should keep. The Univega looks pretty with its pearl white frame but I can't help but feel that I'm cheating on my Motobecane which has been good to me. But I want to keep just one.
Also, is there a way I can fit the rear Weinmann on to the Moto?
I'm going to be the dissenting vote here and suggest the OP keep the Nuovotech 450. It is marginally lighter, has the advantages of more modern equipment (ie. indexing, an extra cog, SLR brakes) and frame amenities (braze-on shifter bosses, dual bottle bosses, pump peg, etc.). While the Eaxge group is not exactly high end, it is better performing than the mix on a late 1970s GT and certainly compatible replacements are easier to find. BTW, isn't a late 1970s GT tretubi Vitus 172, as opposed to Vitus 888? While the GT may have more appeal among the vintage enthusiasts here, it also means the OP may get a better price on the GT.
Your Motobecane may become lonely after the Univega leaves the shed. I would keep both. If space were an issue(with my wife) I'd tear down the Univega and stash parts around the house/appartment. Frame behind the washer, wheels in the back of the closet, cranks in the trunk of the car with the spare tire... etc. Then it still looks like you only have one bike.
*edit* psst... don't listen to me, I've got 40+ bikes in various states of disrepair out in the barn at the moment.
Of course, I can't promise you won't miss the old Moto.
If it were me, I'd just hunt around for a replacement 27" wheel. Put a wtb on Craigslist, or check around local bike shops. It shouldn't cost much for something with a decent hub and alloy rim. The gearing is up to you and depends on the terrain you ride in. Something like 14-28 is pretty standard. Here in the midwest I prefer something with a tighter range like 14-19, 14-21 or 14-24. Depends on your chainrings sizes and how you ride, too. Play with this: http://www.sheldonbrown.com/gears/
