Not long ago I finally picked up my Motobecane. A Grand Jubile of what looks to be 1978 vintage. The bike is the one I wanted when I bought a Nomade in 77 b/c I couldn't afford anything higher up the line.
The question is should I switch to 700C wheels from the stock 27"? I've broken the question down and still am unsure though I'm, at the moment, leaning towards swapping.
I have a wheelset so money is not an issue and my first trial shows that the brake arms have enough room for adjustment.
The stock: Rigida rims on Normandy high flange hubs. Hubs and rims are clean but the spokes aren't stainless steel and have lost their shine. They look kinda crappy to be blunt and not up to the standards of the rest of the gold and brown bike. I'm biased but vintage Motos have as nice a finish as you'll find.
The replacements: Sun rims on early 70s Campy Record hubs. Stainless steel spokes.
Weight as guessed by my calibrated right arm appears to be a wash. The stock set has a SunTour Winner 5 speed freewheel and the other has a DuraAce "ultra" 6 set up though freewheels are interchangeable.
