Topeak MidLoader 4.5 L black

Topeak MidLoader 4.5 L – compact, water-repellent frame bag in black

The Topeak MidLoader 4.5 L cleverly utilizes the unused space in the frame triangle, making it ideal for short tours, day trips, or as additional storage on longer bikepacking adventures. With a volume of 4.5 liters, it offers ample space for tools, spare parts, or food—while remaining extremely space-efficient.
Made from lightweight, highly water-resistant materials, the bag can be easily attached to the frame thanks to its hook-and-loop fasteners. Two water-resistant zippers allow quick access to the contents from both sides.
