Zipp's Speed Box offers the convenience of the classic top-tube box with a few new features to make it more user-friendly. A zipper running parallel to the top tube let's you access its contents and stay focused on nailing that bike split. A thin layer of padding in the side panels protects whatever you’re carrying and helps keep your keys from rattling. Zipp also placed a reflective strip around the whole box to add a little extra visibility.
