Topeak MTS Strap Mount TrunkBag DXP Rack Bag with Expandable Panniers

Dual molded side panels combine with flexible 600 denier fabric to form a semi-rigid, weather-resistant trunkbag. Divided main compartment and side panels expand for extra storage capacity. A rear water bottle holder lets you carry more water on extended trips. Attached with integrated straps. Pannier deployment requires a beam rack with side frames attached or a traditional rack with struts to prevent panniers from contacting the rear wheel.
