Recently I had my bike stolen and I've been depressed ever since. Since getting into fixed gears over the past few months I've learned a lot more about bikes overall, yet still not enough to understand all the components and what's best. Recently I've been looking into getting either a pure fix track Series, state bike co., or aventon Mataro frame. Any have any suggestions on witch frame would be best, or any other suggestions at all? I'm not trying to break the bank overall on the whole bike I plan to spend under 700$.
