ORTLIEB Seat-Pack QR Saddle Bag - black matte/13 litres

ORTLIEB Seat-Pack QR Saddle Bag

Item number: 87542

The ORTLIEB Seat-Pack QR saddle bag with clever lever attachment

The waterproof Seat-Pack QR saddle bag from ORTLIEB with a volume of 13 litres can be quickly and securely attached thanks to the Seat-Lock mounting system with mounting levers - even on lowerable seatposts. When sealing the roll closure, an air release valve ensures that you keep excess air to a minimum and the pack size remains as small as possible. You can open this valve comfortably with a handle loop. Compression straps and the bag's internal rigidity ensure that it holds its shape. The bag includes a number of additional features: a drawstring at the top allows you to quickly secure items such as arm warmers, for example. You can attach a rear light to the daisy chain at the back. If the bag comes into contact with moving tyres, a plate on the underside protects against damage. Strong reflectors make you more visible in twilight and darkness.

Seat-Lock System
ORTLIEB's Quick Release Seat-Lock system enables fast and secure attachment of the saddle bag. At the top is a rail with adjustable levers, which you can use to adapt to the conditions of your saddle area. Depending on the load weight, different areas are marked on the rail where the assembly levers must at least be located. To fix the levers, which is only necessary once per setup, simply use a hex tool. Once aligned, attachment is a snap: attach, push down the levers on the left and right, tighten the compression strap again, done. A classic hook & loop fastener secures the bag to the seatpost.

Hab noch nie eine Tasche gefahren, die so stabil am Sattel sitzt und quasi gar nicht wackelt. Auch das Befüllen geht dank des integrierten Ventil super einfach.
Einziger Nachteil: sie passt nicht an jeden Sattel.

Top Tasche!! Sie passt nach Einstellung ohne Probleme an meinen Sattel ( SDG Bel Air 3.0) und ist dann sehr schnell montiert. Herausragend ist aber vorallem die Steifigkeit. Das lästige schwingen einer klassischen Seat Pack (wenn nicht komplett perfekt gepackt), ist hier praktisch gar nicht mehr der Fall. Das macht diese Tasche für mein Bike Packing set up schon jetzt unverzichtbar.

Tasche sieht gut aus und ist auch sehr stabil. Leider an meiner Specialized Diverge Sattel nur mit sehr viel Mühe in der untersten Einstellung (max. 3Kg) zu befestigen. Alles was höher ist (Einstellplatte verschoben) passt nichtmehr an den Sattel. Daher leider auf die ursprüngliche Ortlieb A****rakete zurcükgekommen...
