Most all of my cruisers start out stock 44 tooth front, 18 rear. That's unless you are running a skiptooth. If I have difficulty climbing with some of my heavyweights (60+pounds), I just gear down the rear. You should be able to get up to a 20 tooth without having to add any links. You can go to a 22 tooth for some really low gearing, but you will have to add at least a half-link to get it to fit. All of this will keep your ride looking stock to most people.
