When youre spending quality time in your aerobars, its nice to have a butler at the ready to hand you the food and drink you need to keep going. Only butlers cant keep up. Its for this reason Zipp created a line of Speed Box Frame Bags to mount behind your stem and on top of the top tube. This it the smallest of the line, the 1.0.

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 smallest bag in the line, the 1.0 measures 231.8mm long by 67.4mm tall by 42mm wide. Its not big, but the length allows for things like bars to easily fit.

The Zipp Speed Box 1.0 is the minimum you need to keep your feed handy.
