Ortlieb Back-Roller Core QL2.1 Pannier

The QL2.1 mounting system is highly versatile and fits rack tube diameters of 8, 10, 12, and 16 mm. It is designed to be tool-free, so you can easily adjust the hooks to match your rack's width without needing extra equipment.

This bag is fully waterproof with an IP64 rating. The combination of durable, PVC-coated polyester fabric and a roll-top closure ensures your gear stays dry even in heavy rain or road spray.

The bag offers a 20-liter capacity, which is standard for a single rear pannier and sufficient for a daily commute or a weekend trip. It is rated for a maximum load of 9 kg, so be mindful of the weight if you are packing heavy items like tools or electronics.

The Back-Roller Core features a single, large main compartment. This design prioritizes simplicity and maximum storage volume, though it means you may want to use small packing cubes or pouches if you prefer to keep smaller items separated.

Safety is a priority with this model, which includes highly reflective Scotchlite elements on the sides. These are designed to catch headlights and increase your visibility to drivers in low-light conditions.

Not at all. The QL2.1 system is designed for quick, one-handed operation. You simply pull the handle on top to open the hooks, place the bag on your rack, and release the handle to lock it securely in place.
