Nice bike! You've got it set up similar to what I did with my (aluminum) Specialized Sequoia. It came with a low-end drivetrain that I converted to a 105 triple. I also discovered the "secret" that 700x28 or 700x32 tires (which just fit) improve the ride tremendously and give up very little if any on the real-world, real-road performance factor. The bike also came with fender & rack mounts and I put a fixed rack on it.

One innovation that I'll be trying out on a tour next week is that I changed the 30-tooth inner ring for a 24-tooth for added help on the big hills. I have to be a bit careful since I can only use that safely with the inner (larger) 3 or 4 sprockets, but then that's the only time that I expect to really need it!
