Restrap Downtube Bag

The Restrap Downtube Bag maximises carrying capacity by utilising the often-overlooked space beneath the downtube. Perfect for smaller frames or riders needing additional storage, this bag provides 1.2L of fully waterproof space, easily attached with velcro – no bosses required.

Its waterproof construction features a roll-top closure, keeping contents protected from the elements, road spray, or trail debris. A single integrated velcro strap secures the bag firmly to the downtube, minimising movement and rattles, while a stitched-in grip pad prevents sliding. The bolt-free design allows for quick and effortless swapping between bikes.

Ideal for storing spares, tools, or heavier items, the Downtube Bag helps maintain a low and centralised centre of gravity, improving handling. It is particularly useful for bikes with dropper seat posts or setups that make traditional tool pouches impractical.

Compatible with all bikes, it fits downtubes up to 19 cm in circumference and offers versatility for alternative placements, such as cargo cages or seatposts.

Handmade in Yorkshire, the Downtube Bag is finished with Restrap’s signature vegan-friendly PU label.
