Topeak MTS TrunkBag EX

The Topeak MTS TrunkBag EX uses a universal hook-and-loop strap attachment system, which is designed to secure the bag to almost any standard bicycle rack currently on the market.

The bag is constructed from weather-resistant 600 denier fabric, which protects your gear from light rain and road spray. However, it is not fully waterproof, so we recommend using a dry bag or cover if you frequently ride in heavy downpours.

Yes, the main compartment features rigid foam insulation that helps maintain the temperature of your items. It is perfectly sized for keeping a few drinks or snacks cool during shorter rides.

The bag includes a detachable shoulder strap that clips on easily, allowing you to carry it comfortably off the bike like a standard messenger bag or satchel.

With an 8-liter capacity and three distinct compartments, there is plenty of room for a spare tube, multi-tool, tire levers, and a pump, with space left over for a light jacket or lunch.

Yes, thanks to its semi-rigid construction and EVA foam padding, the bag maintains its structured shape even when it is completely empty, making it easier to load and unload your gear.
