ATTK

What Our Gearhead® Experts Are Saying:

"The ATTK Top Tube Bag line covers both ends of what riders actually need from top tube storage. The S is the one I reach for on mixed-terrain days where one-handed access and low weight matter most, and the XL is what I spec on builds where nutrition volume and cockpit aerodynamics are the priority. The cable pass-through on the XL is genuinely useful on modern internally routed frames, and both sizes install cleanly with or without dedicated braze-ons."

Top tube storage earns its place on a performance build when it solves a real problem without creating a new one — whether that's bulk in the pockets, drag at the front end, or a cluttered cockpit on a cable-routed frame. The Profile Design ATTK Top Tube Bag puts nutrition and essentials exactly where they're easiest to reach, with waterproof construction, fast zipper access, and mounting options that cover direct bolt and strap attachment across virtually any road, gravel, or triathlon setup. Available in two sizes to match the carrying demands of the ride, it's the kind of addition to a build that quietly improves every outing it's along for.
