Hours into a long ride, the Apidura Racing Top Tube Pack opens with one hand, thanks to a magnetic flip-top that runs the full length of the pack. This waterproof top tube bag closes as easily as it opens, and seam-welded Hexalon, a lightweight laminate, keeps the contents dry. What Our Gearhead(R) Experts Are Saying:"The two straps around my top tube and the one around the steerer went on without tools. The pack stayed put through full days of riding, and the closed-cell foam padding cushioned it against my frame."
