Also bear in mind the landscape of the area you're moving to. Where abouts are you going to be living/riding? Gear ratios are an area to research, although it's pretty hard to understand properly without experimenting and seeing what people mean when they talk about how much your tooth count can transform your riding experience. Probably good to aim for a standard 48tooth chainset and you can swap cogs out pretty easily if you've got the right tools (chainwhip, lockring tool, chain link remover if you decide to change cog size by a considerable amount). There's a thread on ratios somewhere too
