Hi all, First post here. I'm a London commuter, using a Brompton to go partly by train at the moment. After about a year of doing that I'm ready to cycle all the way in to work now (at least on some days) - it's not all that far, about 7 miles, but as you might know cycling in central London is not always the best fun. I'm also interested in going on some runs with my local cycle club. I have a Trek hybrid at the moment but am looking to replace it with a road bike, as I would prefer a lighter bike and dropped handlebar riding position. I'm wondering whether to go for a modern road bike - something like the Genesis aether10 is roughly in my price range, or go the ebay route and get a bike with Reynolds 531 frame or similar, and maybe spend some money on doing it up. Lifting bikes like the Genesis in a shop, it seems really light (alu frame). Would a steel framed bike be significantly heavier? I'm looking for something quite flexible, as it would be for commuting / modest touring, but I also like pushing on and going fast so I'm looking for something nippy. Thanks for any pointers!
