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 centimeter 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. OTHER PRACTICAL FEATURES: + Our reflector ensures added visibility and safety + A daisy chain allows for the attaching of a rear light COMPATIBILITY NOTICE YOU CAN EASILY CHECK IF YOUR SADDLE IS COMPATIBLE: 1.
