Ideal for extended tours in any kind of weather, the Ortlieb Bike-Packer Classic Panniers Pair accompany you on multi-day journeys with plenty of space and robust protection. The durable nylon construction is abrasion-resistant to handle rougher rides, while a lid with snow flap keeps moisture and dust at bay. The QL2. 1 mounting system attaches to racks with a maximum diameter of 16mm and adjusts without the need for tools—it also comes with reduction inserts to accommodate tubes with diameters of 8mm, 10mm, and 12mm. Ortlieb fortified this bag with an edge protector to prevent contact with spokes and trail debris, as well as highly reflective 3M Scotchlite reflectors to give you substantial visibility for added safety on darker rides.
