fixed gear for nyc?
i live in new york city and frequently ride laps around the central park loop. it's 6 miles and is moderately hilly. i currently have a road bike, but i'm thinking of getting either a track bike or converting something to a fixed gear myself (for a fun project). my riding is mostly a blend between heavy traffic streets and the relatively open road of central park.
would a track bike\fixed be good for this? i'm leaning toward the fuji track pro if i decide to buy new, but i'm a little worried about not having a front brake, because i often have close encounters with cars and need to be able to stop quickly. anyone out there ride in a smiliar environment?
