Restrap Downtube Bag

Add extra carrying capacity without compromise. The Restrap Downtube Bag makes smart use of the space beneath your frame, ideal for smaller bikes or riders who need that bit more room for essentials. Handmade in Yorkshire, this tough 1.2L waterproof bag is built to handle whatever the road or trail throws at it. Its roll-top closure keeps contents dry and secure, while a single integrated Velcro strap ensures a tight, rattle-free fit. A stitched grip pad prevents slipping, and with no need for mounting bolts or bosses, it swaps easily from bike to bike in seconds. Designed to hold spares, tools, or heavier items low and central, it helps maintain your bike’s natural balance, especially useful if you’re running a dropper post or a full bikepacking setup. Compatible with all frame types, from slim steel tubes to 19cm downtubes, it’s as versatile as it is practical. Finished with Restrap’s signature vegan-friendly PU label, the Downtube Bag embodies Restrap’s commitment to simple, durable, and functional design, made by hand and made to last.
