Hi all:

just picked up a new ride for my wife; it's a 1976 Motobecane Grand Touring mixte, dirty but seems to be in good shape. Very lightweight Vitus frame, no more than 25 pounds. It's all original except for the crankset. A previous owner replaced the original SR AX-5 cranks with vintage Sugino Mighty Tour, with 44 and 34t chainrings - I guess they REALLY didn't want to go too fast! I believe this crank takes 110 BCD chainrings. So, I want to bring it closer to the original 40/52t gearing. Is this simply a question of finding the proper size chainrings and replacing them? I'm assuming the front derailleur will need to be raised slightly to accommodate the larger size? Anything I'm missing here?

I'll post pics when I've had a chance to clean it up.

Thanks

Roy
