Ortileb Seat-Pack QR 7.5 L  The innovative and patented Seat-Lock system ensures that the Ortlieb Seat-Pack QR saddle bag is firmly attached yet easily removable in seconds. With the addition of a special 4.3 cm adapter, the bag can even be used with a dropper post, making it compatible with a variety of bike setups. This flexibility means you can switch between bikes without fuss or additional tools. Stable Packing and Organised Storage The Seat-Pack QR features internal reinforcement and five compression straps to keep your gear tightly packed and stable while riding. A valve with a handle strap allows for additional compression of the pack volume, while an external elastic cord provides options for attaching extra items such as a jacket or accessories. Durable and Protective Design Made from abrasion-resistant nylon, the Seat-Pack QR is built to withstand tough conditions. The protective plate on the underside prevents damage from tyre contact and doubles as a fender, keeping both your bag and your bike in top condition. Fully waterproof, this saddle bag ensures your equipment stays dry and secure, whatever the trail or weather. Designed with practical cycling needs in mind, the Seat-Pack QR offers quick attachment, secure storage and reliable protection, making it an essential companion for every ride.
