Wow, that's great service from your bike shop!

Your load sounds OK - I usually roll with about 45-55 pounds (gag), and it's fine on the flats and too much on the hills. I'm working on trying to reduce it. If you can get rid of anything, do. After the first week, re-evaluate and mail stuff home that you don't need. Pay attention to what shoes & clothes you bring, in terms of what they weigh.

Hope you have a great ride!
