Top Tube Bags

Top Tube Bags—often called bento boxes—get their nickname from their purpose: easy, organized access to the essentials while you ride. A long-time staple in triathlon, these compact bags have evolved well beyond race-day use and are now a popular choice for road, gravel, and everyday bikes.

Originally designed to hold gels and small nutrition items within quick reach, modern top tube bags are just as commonly used for phone storage, keys, cards, and other ride necessities. Their streamlined position keeps contents secure without interfering with pedaling or handling.

Our best-selling top tube bags are those sized to comfortably fit today’s larger smartphones, making them ideal for training, commuting, and long rides alike. A standout favorite is the Zipp Speed Box 3.0, consistently chosen for its capacity, stability, and clean integration with the bike.
