Thanks to the unique Seat-Lock attachment system the Seat-Pack QR is quickly and securely mounted and just as speedily removed completely residue-free. An adapter even enables the use of a dropper post making the innovative Seat-Pack QR suitable for a variety of bikes. Whether you’re riding singletrack mountain passes or gravel routes with the waterproof Seat-Pack QR you are ready for every bike adventure. With the innovative and patented Seat-Lock attachment system and abrasion-resistant nylon fabric the bag is super stable quickly mounted and just as quickly removed without leaving any residue. And with the help of a special adapter of just 4.3 centimetre in width this bag can even be used with a dropper post. The internal reinforcement and five compression straps ensure that the contents are packed tightly and securely. A valve with a handle strap helps to compress the pack volume and the elastic cord on the outside allows for the attachment of additional gear. To prevent damage from tire contact a protective plate is attached to the underside of the Seat-Pack QR which also doubles as a fender.
