Description The Apidura Expedition Bolt-On Top Tube Pack is a boss-mounting, waterproof bikepacking bag for storing your essentials on the ride. You will be able to fit your phone, power bank or snacks in this little bag. And using your top-tube accessory mounts means it will be exceptionally stable. Top-tube bags are super useful for immediate storage. Because digging around in your frame bag for something which has migrated to the back is frustrating! And a good bikepacking set-up is a well organised one, where everything has a home. Giving your most important and most used gear the priority position of your top tube is good organisation! And Apidura know you will use this as a power-bank storage area so there’s a waterproof zipper protecting your gear. And a port hole for running a cable through it without letting the rain in. This bolt-on bag is cut from a three-layer laminate fabric that was developed specifically for Apidura. The material is lightweight, and is highly resistant to tears and abrasion. Notably, it’s welded together at the seams, creating a watertight seal that ensures the top tube bag remains completely waterproof. Two tool-free attachment bolts included.
