5 gear casette or freewheel? I suppose it's an old classic, and you could go on ebay and look for a NOS replacement cassette and a new chain, even derailleur. Maybe you have a repair shop in town with an interest in older bikes? If you can become friends with non-indexed gears and the rims are fine this is not a bad idea. I like old racer frames with lugs for everyday cycling, they are often very underrated. If you want a 7,8 or 9 gear casette you need a new wheel, and all gear parts replaced from handlebar down to the back hub. The old 5 speeds lasted much longer, didin't wear down as fast, but the new racer gears are really nice too, slide up and down surprisingly smooth.
