Zipp Speed Box 3.0

Zipp’s Speed Box 3.0 Frame Bag is a big trough for the top tube of your bike. It can stow things like a tube and tools, but it’s probably better for your nutrition, as it’s nice to have that stuff handy when riding the aerobars for a long time. All the bags have three Velcro straps, a rigid EVA exterior, and a zipper to keep everything inside. The straps are set up with one going forward to secure to your stem. Two are underneath the bag to secure to the top tube. The rigid structure works for aerodynamics. And the zipper, which is water-resistant and seam-sealed allows for easy access from the top. As the big bag in the line, the 3.0 measures 218.6mm long  by 108.4mm tall by 42mm  wide. It’s like having a lunchbox behind your stem. The Zipp Speed Box 3.0 has your meal at the ready.
