The Topeak MTX TrunkBag DX with Police logo is a durable, medium-capacity rear rack trunk bag designed for commuting, patrol riding, and everyday cycling storage. Built using Topeak’s unique construction process combining molded panels with flexible fabric, this bag delivers excellent rigidity and water repellency while maintaining a sleek profile on your bike. With 12.3 liters of capacity, it features a divided main compartment, two zippered side pockets, and a multi-expanding top section for extra storage when needed. The rigid EVA foam insulation helps the bag keep its shape while protecting your gear from bumps and vibration. The MTX QuickTrack mounting system allows fast, secure attachment and removal from compatible Topeak MTX rear racks in seconds—perfect for riders who frequently load and unload equipment. Added features like a rear water bottle holder, elastic top bungees, shoulder strap, carry handle, and a safety light clip make this trunk bag extremely practical for daily use. Finished with a 3M reflective strip for improved nighttime visibility and compatible with an optional rain cover, the MTX TrunkBag DX is a reliable storage solution for cyclists who want organized capacity without the bulk of full panniers.
