Looks like a nice bike. What a great present, huh? Apart from having a road bike, it sounds like you're also picking up some knowledge and wrenching experience (with bikes, anyway).

You might want to think about replacing the tires. Sooner or later, they'll wear through and you'll have to. But the ones you have now are slowing you down while you're on the road. If most of your riding is on the road, a pair of good slicks will help a little to make up for gearing and weight issues.
