ORTLIEB Back-Roller QL2.1 40 L

The ORTLIEB Back-Roller Classic QL2.1 panniers are sold as a pair and are a well-established choice for cycle touring, commuting, and everyday loaded riding. Each pannier holds 20 litres (40 L in total) and measures 42 × 32 × 17 cm — a practical size that distributes weight evenly on either side of the rear wheel. The shell is made from PVC-coated polyester: PS490 on the sides for abrasion resistance, and PD620 on the front and rear panels for added durability. The roll-top closure creates an IP64-rated waterproof seal, keeping out dust and water spray from all directions, whether you're caught in a downpour or riding through puddles. The Quick-Lock 2.1 system lets you attach or remove each pannier with a single motion — no tools required. Included adapters (8, 10, and 12 mm) ensure compatibility with most rear racks up to 16 mm tube diameter. The symmetric design means either pannier can be used on the left or right side of your rack. Inside, a zipped mesh pocket keeps smaller items organised. The included shoulder strap means you can carry the pannier hands-free once you leave your bike. Large-format 3M Scotchlite reflective panels improve rear visibility in low-light conditions without needing additional lighting accessories.
