Ortlieb Bikepacking Seat Pack QR Seat Bag - 13L Black. Thanks to the unique Seat-Lock attachment system the Ortlieb 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. The internal reinforcement and five compression straps ensure that the contents are packed tightly and securely.
