I'm looking to buy a new single speed my last was a pure fix.. I know **** quality, but it was my first purchase and introduction to cycling. I rode it for over a year, and I'm looking to buy something of a way better quality. I have about 1000 to spend, my question is am I better off buying from a factory, or should I do a custom build. No preference on frame, steel is nice, but I'm open to aluminum frames as well. I want the best quality that I can get for that price. I know that opinions vary on best brands, etc.. but I'm open for any suggestions.
