The Arundel Top Tube Tycoon is a bento-style storage bag designed for rides where you need more than what fits in your jersey pockets. It mounts to your top tube and holds 40 cubic inches of gear—enough space for a spare layer, snacks, tools, your phone, and whatever else you're carrying for the day. The tapered shape keeps it out of the way when you're pedaling, and the single-handed zipper makes it easy to grab what you need without stopping.

The bag uses welded-seam construction with water-resistant materials.

The bright orange interior lining helps you spot what you're looking for quickly. A padded plastic insert maintains the bag's shape and stops it from rattling against your frame when it's partially full.

If not, the included velcro straps secure it just as well—you can tuck the straps underneath when using the braze-ons. The bag measures 8.5 inches long, 3.5 inches tall, and 1.75 inches wide.
