The Nomade is Moto's entry level bike. High tensile frame and low end components? You paid about FMV for the as is condition of that bike. I bought one a year ago for $20 that needed a full overhaul. They ride nicely though, despite their weight. I would clean and overhaul the bike, replace the consumables, and not change the rims. Standard ten speed chain, about $9.00.
enjoy!
