I would never go on a long distance tour without my handlebar bag! It is where I keep items I would like to access quickly and easily without having to get off of my bike – items such as my camera, energy snacks, tissues, keys, wallet, money, ID, passport, a map in the top window, etc. . . and I also use it for a waste basket. When I ride up a mountain pass, I often find myself so focused on the ride that I don’t want to stop for photos. With a camera living in my handlebar pack it is easier to talk myself into pulling off the road for a quick photo opportunity – without having to dismount the bike. I can just step down, straddle the top tube, take a quick photo and be back in the saddle in seconds – so I don’t mess up the rhythm of my climb. And later, I don’t regret missing the photo. If I need to take a restaurant or restroom break, the handlebar bag comes off the quick-release bracket, and STAYS WITH ME on the shoulder strap, so I don’t risk having such critically important items stolen. If you have not used a handlebar pack on your tours, you just don’t know what you have been missing!
