so I'm 6' 175 and I want to start racing track. I've been riding fixed gear for a bit and want to take it to the next level. I want to get a bike I can race with but my budget is probably around 800 total. Whats the best way to hit that and still have a bike I can be proud of. I said my size because I usually find used bikes that are too small so its not easy finding a used bike.
