Introducing the new Downtube Bag, an all-purpose down tube bag.

New product available in the shop: Downtube Bag

The Downtube Bag allows you to utilize the space beneath the downtube that usually goes unused. Designed to be mounted even on frames without dedicated mounting bosses, it simply requires tightening the straps; the bag remains securely attached beneath the tube—even on MTB trails—thanks to a “grip” material sewn onto the straps and the section in contact with the frame.

Key features

Available in all our material options: VX21, X10, X51, X33, Liteskin

Features an internal HDPE structure that can be drilled and bolted directly onto frames with existing mounts

Allows for carrying bottles up to 1.5L (unlike a standard bottle cage);

However, this can only be used for storage, as neither its position nor its mounting system allows for use while pedaling.

It offers the great advantage of versatility, allowing it to carry anything else you might need—such as mechanical repair tools, a spare inner tube, or even a tent (provided it fits within the dimensions).

NOTE: Due to potential clearance issues, you must ensure the front wheel does not touch the bag; with the correct fitment, it works easily on 29″ and 27.5″ MTBs, or 26″ bikes with rigid forks. The bag is not designed for use on a fork without specific mounts (e.g., Anything Cage).

Dimensions: 23.5 cm (min. height) – 29 cm (max. height) x 9 cm (diameter)

Weight: VX 21 -> 120 g / X51 -> 127 g / X10 -> 132 g / Liteskin -> 120 g / X33 -> 122 g

Capacity: 1 L / max. 1.5 L

Please note that although the fabric is waterproof, heavy, prolonged rain may allow some water to seep through the seams. We therefore recommend packing any items that must remain completely dry inside plastic bags.
