Topeak Loader Midloader bicycle bag (under frame 4.5 liters)

The Topeak Loader Midloader is a versatile under-frame bag designed for bikepacking and touring. With a 4.5-liter capacity, it offers ample storage for tools, spare tubes, or snacks while keeping weight low and centered. Made from durable 600D polyester with a PVC backing and welded seams, it is fully waterproof to protect your gear in wet conditions.

Installation is quick and secure using three hook-and-loop straps that attach to the top tube, down tube, and seat tube. The bag features reflective strips for increased visibility in low light, and a roll-top closure ensures easy access and a tight seal. Compatible with most frame geometries, it is an essential addition for any long-distance cyclist.
