Had to go to NYC the other day for work and came across this Centurion right outside Grand Central. There were a few other fixed gears chained to sign posts around the station. One was black with riser bars and white letters on the downtube spelling MOTH. Half of the "H" was obscured so it could have said MOTHER but I don't the F word would have fit.
I call it a Ghetto Fix because the bars have no grips and the double chain ring. Love the one brake. The Moth bike was set up similarly.
