NYC is pretty much a 700c town, fixies are more common than vintage MTBs but you do see them every day.

This was taken around where that picture was taken, I flatted and being me had a tube but no means of inflation. I had to flag down a bike bro who gave me his last gasp of co2, enough to get home. 91 Haro Extreme, with 2.3" DTH tires for extra cush.
