Topeak MidLoader

The MidLoader is designed to fit most standard frame geometries, but you should measure your frame's triangle space against the bag's dimensions of 54.5 x 13.5 x 6 cm. It is compatible with top tubes between 45-66 mm, down tubes between 38-70 mm, and seat tubes between 28-60 mm.

The bag is constructed from water-resistant materials and features weather-resistant zippers, which will protect your gear from light rain and road spray. However, it is not fully waterproof, so we recommend using dry bags for sensitive electronics or clothing if you are riding in heavy, sustained downpours.

The MidLoader is rated for a maximum load of 6.5 kg. Because it mounts in the center of your frame, it is an ideal spot for heavier items like tools, spare tubes, or food, as this helps keep your bike's center of gravity low and stable.

Depending on your frame size and the positioning of your bottle cages, there may be some interference. Because the MidLoader occupies the main triangle, you may need to use side-entry bottle cages or relocate your bottles to other mounting points on your bike.

The hook-and-loop fasteners are designed to be reliable and secure for off-road use. They provide a tight, stable fit that prevents the bag from swaying while you ride, though it is good practice to check that the straps are pulled taut before starting a long ride.
