The Sport-Packer Plus is a classical waterproof rear pannier made of robust polyester fabric with plenty of room for everything you need on tour. Simple mounting is guaranteed by the QL2.1 fixing.
Ortlieb's QL2.1 mounting system uses hooks to attach the pannier to your bike rack without the need for any tools. This means the panniers can be easily switched from one bike to another. Inserts can be used which allows the hooks to attach to racks of 8, 10, 12 or 16 millimetres in diameter.
