Topeak Aero Wedge DX Seat Bag – Quick-Attach Medium Capacity Black Bike Bag

Aerodynamic Under Seat Bike Bags: Designed for Efficiency & Safety

For cyclists seeking seamless performance and secure storage, our under seat bike bags combine cutting-edge design with practical functionality. Engineered with an aerodynamic wedge shape, these bags slice through wind resistance while maintaining stability on even the fastest commutes. The innovative internal compartment system organizes tools, spare tubes, and essentials in separate zones, preventing damage during rides.

Constructed from rugged 1000-denier Cordura Plus fabric, these bags withstand trail wear and tear while covered zippers ensure contents stay dry in rain or humidity. A built-in taillight mount enhances visibility, and 3M reflective strips wrap around the bag for 360° nighttime safety—perfect for urban commuters or mountain trails.

Choose Your Size:
– Medium (7.5″ x 3.7″ x 3.9″): Compact yet spacious for daily essentials like keys, phone, and multi-tool.
– Large (9.1″ x 5.1″ x 5.5″): Ideal for longer adventures with extra room for pumps, snacks, or repair kits.
