Hi, just wondering if I can get some advice. I just purchased an 80's (maybe early 90s) peugeot for my sister. It's kinda a women's hybrid to best describe it I guess. So I'd love to remove all of the "noise" meaning the extra - the derailleur, the extra gears, the shifters, "the noise" as I like to refer to it. Anyway, anyone know how I can do this easily and cheaply? She'll be riding in relatively flat situations and the one gear should work and make the bike lighter and more manageable.
