Ortlieb designs the Back-Roller pannier for cyclists who don't want to compromise when facing the challenges of everyday life, whether it's a rainy city commute or a long, loaded bike tour. With a 20-liter capacity and an IP64 rating, it combines generous storage space with proven protection against dust and water splashes. The waterproof zippered front pocket and removable shoulder strap round out a design intended for use both on a bike rack and carried by hand.

Protection and Water Resistance of the Ortlieb BACK-ROLLER 20L ZP QL2.2 TS Bag

The roll-top closure provides the first level of protection for the contents: by folding the top flap over several times, it creates an effective barrier against water and dust, without requiring any mechanical parts that could wear out. The TIDURA® strong fabric, combined with PU-coated Cordura, offers abrasion resistance suited to the demands of daily transport. The IP64 rating certifies protection against water splashes from all directions, providing peace of mind during outings in wet weather. The waterproof zippered front pocket allows quick access to everyday items—such as maps, keys, or a phone—without having to unroll the main bag.

Mounting and Everyday Versatility

The Quick-Lock 2.2 system lets you attach or remove the bag in a single motion, without tools. It’s compatible with racks whose tubes have a diameter between 8 mm and 16 mm, covering the vast majority of mounting options available on bike equipment on the market. The removable shoulder strap transforms the bag into a shoulder bag as soon as you get off the bike, without any complicated adjustments. The side reflectors help improve visibility in low-light conditions—a detail that matters during morning or evening rides.

Construction and Dimensions

Measuring 42 cm high, 32 cm wide, and 17 cm deep, the Back-Roller 20L offers a structured interior space for organizing a change of clothes, rain gear, or daily groceries. Weighing 836 g, it remains relatively lightweight for a bag of this size and durability. Manufactured in Heilsbronn, Germany, it comes with a 5-year manufacturer’s warranty on materials and workmanship, reflecting high production standards.
