In a few weeks I'm going to ride from rural Utah to NYC and stay with a friend in Whitestone. I'd like to see the city, and thought doing it on my bike would be cheaper than taking public transportation, but I don't know what kind of lock I'd need. I used to live in San Jose, and have a Kryptonite Fahgettaboudit. But that's pretty heavy to take on a tour, and more than I need for where I live now, so I'm thinking about downgrading. What kind of lock should I have in New York? Here's a picture of my bike; will thieves even care about a touring bike?
