Ideal for commuters, utility cyclists and tourers who use an MTX QuickTrack® 2.0 rack and want organised, off-the-back storage for everyday rides.
The MTX TrunkBag EX is a structured rear rack bag with 8 L of storage in a divided main compartment, plus two side zippered pockets and a multi-expanding top. It is sized for daily essentials, commuting equipment, shopping or a light touring load, while the rigid-panel and flexible-fabric construction helps it retain its shape.
Mount it directly to an MTX QuickTrack® 2.0 rack, or use the MTX QuickTrack Adapter 2.0 where compatible. The 600 denier polyester outer and rigid EVA foam insulation provide structure and help protect your belongings, while the construction offers water repellency for everyday riding. The maximum load remains limited by your rack’s own rating.
For practical day-to-day use, you get a water bottle holder, mesh pocket, reflective elastic cord, carrying handle and detachable shoulder strap. A 3M™ reflective strip and safety light clip add useful visibility options when riding in lower light.
