Hi! My bike seat and post was stolen today, and I was wondering if anyone could reccomend the best shop in NYC (Manhattan or Brooklyn) to get a new seat/post for cheap, possibly used. I usually go to Bike Habitat, but it seems a little expensive/high end for my needs (I have a Mongoose Alta mountain bike with road tires).
Also, I've heard about locking pin system for wheels and seats that requires a key to open them? Can anyone tell me more about this/where to get them? Thanks!
