Fortunately they don't make bikes out of copper so I've gotten by with a heavy cable lock, I don't think that bike theft is too big of a problem here (Fort Worth), unless you make it too easy for them.
When telling people I bought a Specialized Tricross bike most just have that blank look on their face (like when they tell me about the mods to their cars or Hawgs), and are probably wondering "What is Tricross, and why you need a special bike for that?", so unless you have a strong bike culture there, most people have no idea what they are looking at. I never thought I would spend close to $2k for a bike, so yeah there was some paranoia in leaving it locked up somewhere, then there was the realization that most people here will see the bike, but they don't look at the bike.
I've had a Tricross Comp Double for almost a year now and the only drawback is my foot hitting the front wheel sometimes when I turn (so I put fenders on to make sure it happens more often). Other than that, there are no complaints. I've ridden it all over the place and even jump the occasional curb with no worries. Loaded up the panniers coming from the store, no problems.
Glad to see there are others out there with the same idea and bought a Tricross.
