I'm new to fixed gears but I'm already in love. I have a road fixie that I've been riding for a while, but it's too small for me. I mostly use the bike to commute to work and it isn't very hilly. I'm thinking about getting a track frame (De Bernardi Thron Track). Any thoughts on Road Conversion vs. Track? I come from a BMX background and don't have any real experience with either.
