The Coxa Triangle Frame Bag is a compact, versatile storage solution designed for bikepacking, alpine crossings, and extended trekking tours. Made from lightweight, durable 500D/PVC, it is especially suited for carrying heavier items such as tools, tent poles, or food supplies. Its placement below the top tube still leaves space for a water bottle. It a practical option for some full-suspension bikes with limited room depending on the placement of the rear shock. Three robust, adjustable Velcro straps secure the bag to the top tube, accommodating tube diameters from 30 mm to 70 mm, with excess strap length easily trimmed. Two additional Velcro straps provide flexible positioning on the down tube. A zipper provides a secure, weather-protected seal and features a large opening for easier packing. The bag ensures balanced weight distribution on the bike by using the negative space in the bikes frame.
