Hi Everyone! I've been enjoying reading the various forums where people describe upgrading or restoring their older touring bikes. I've got a nice Schwinn Voyageur with a frame in great condition that was given to me by my grandfather in good working order. I've rode it for a couple years now as a commuter bike (school mainly) as well as for recreational longer rides and haven't had any major problems. A bicycle enthusiast friend of mine pointed out that the rear wheel was a little out of true and suggested upgrading the wheels from their current 27" originals (or similar, idk) to the now standard 700c. This sounded like a good idea to me until I started getting confused, looking at the new wheels and seeing 7-10 speed listed, when my bike is currently what they used to call a 15-speed (5 speed on the rear cassette).
So, my main question is this: what's the most reasonable way to switch to 700c wheels, and will this require purchasing a new hub, freewheel, brakes, etc? Has anyone done this on a Voyageur (or similar bike from that era) with great success? I know my way around the bike, having repaired various things, adjusted the brakes, and replaced the chain, so I'm not afraid of making a bunch of changes, I just don't want to break the bank or waste my time.
Thanks for the help!
