In a bid to get fit, do some more exploring, and generally improve my ability to get around the world under my own steam, I'm considering investing in a road bike. I was wondering if any of you did much cycling, and perhaps had some thoughts on where I should start. My knowledge is sadly rather limited; I had a few bikes when I was younger, and supposedly one never forgets, so at least I have few qualms of climbing on the thing. That said, I'd appreciate any assistance that could be offered in the way of explaining the nomenclature, and what I'll need to know to get started. Hopefully this can become one of those ever-useful "exploiting collective knowledge" threads, with some good stories and informative links.
