2 bike shops in NYC have closed as far as I can tell
I tried to stop into Sids on 34th St. a few weeks ago and they were packing up the shop to move, but they didn't have a place to move to and they couldn't tell me much more. I don't know if they have a place yet. They were close to my office so now I don't have a lunchtime shop to wander to.
Also, Brooklyn Bike and Board, or is it Brooklyn Cycle Works, on Vanderbilt Ave also appears to be closed. They helped me out recently when a spoke nipple broke right across the street from them.
