The Zipp Speed Box offers the convenience of the classic top-tube box with a few new features to make it more user-friendly. Pulling sideways on a Velcro® panel can be awkward when you’re focused on nailing that bike split, so we put a zipper running parallel to the top tube.
Solid molded EVA construction.
Water-resistant seam-sealed zippers.
Three-point Velcro® strap attachment.
