Track Star is in Manhattan. King Kog is in btown. Both are DEF worth scoping out. As for locking up in NYC, you can't be paranoid enough. Minimum two locks unless of course your ride is dirty, taped and stickered up. Lose the Brooks while you're at it. Just my best advice if you're only going to be in town one day. Most bike shops have street/bike maps for free. Hope that helps man!
