Top Tube Bike Frame Bag For Waterproof Cycling

Mounted directly to your bike’s top tube, this cycling utility pouch delivers dependable storage without crossing your legs. Measuring 40 by 6 by 12.5 centimeters, the unit provides three liters of protected volume for phones, wallets, tools, and spare tubes. A rigid internal plate preserves the bag’s shape under vibration, keeping contents secure during demanding routes.

All-weather reliability stems from double-sided waterproof glued zippers that seal out rain and road spray. Custom-fit straps with hook-and-loop closures attach through dedicated mounting holes, letting you lock the package snugly against any frame size. Subtle reflective strips boost nighttime visibility, while the streamlined 190-gram build keeps your ride light.
