I'm about to start biking in Washington, DC. Not sure if I'm going to use my old Novara hybrid, or pick up something that I might find more suitable used. Either way, DC is quite hilly (to say nothing of the suburbs!), and I think at my novice level, 10 speeds are a bare minimum. Without converting to 10 cogs in the back and 1 chainring, is there a way to use a chain guard with 2 or 3 rings in the front? I'd like to be able to do my urban biking without fear of getting chain grease all over my leg, and I'm not keen on rolling up my trousers if I'm wearing dressy ones.
