A keg of New Belgium Beer. There is nothing like locking your bike up to a beer keg that is behind your favorite watering hole. They are light but awkward if you try to move or remove the bike from where it is. The bike above is the "Tank Bike" all 58 pounds of it. I was finally able to order a Xtracyle on Thursday. Brown should be delivering it by Wednesday the 26th to the shop. I should be on the road with it by Friday if not before. I can't wait.
