When you need extra storage on the bike, you take it where you can get it. That's why we redesigned our Top Tube Pack to be a smaller, lighter, and out-of-the-way solution for carrying your smaller ride essentials and gear. It's fully-waterproof with a nylon-coated mesh construction, fully-welded seams, and a waterproof two-way YKK zipper. To make it easy to get on and off the bike, it has a simple-to-use, three-point strap attachment system that's now also paired with hard mounts for better stabilization on any frame. This makes it easy to swap between bikes, or to take it off if you're locking up your bike outside for an extended period of time. Designed specifically to fit with our Diverge, this bag has storage capacity that's ample enough for some larger items like a camera, pumps, or extra water. A handy USB port also helps with cord maintenance and use. And despite its amazing storage capacity, it's small enough that small items won't disappear like they've fallen into a black hole.
