I have a nice 1982 Peugeot 5-speed city bike, imported from Germany, 100% stock, Carbolite, cottered cranks, 700c aluminium wheels, chrome fenders, plastic chain protector, chrome luggage rack, generator and lights, swiss BB threads, and a semi-moustache handlebar. It rides very nicely. I found a old beat up Motobecane 10-speed from the mid 70's. Question: Will the handlebar stem and square-taper spindle switch over? I'm pretty sure a Moto that old has French-thread BB so I'd like to just switch the spindle cranks and chainrings, effectively making my bike a 10-speed. I would also like to switch to drop bars. Thanks for any info!
