ORTLIEB Seat-Pack QR 7.5 L

The ORTLIEB Seat-Pack QR 7.5 L is a saddle bag built for riders who want reliable storage without slowing down at the trailhead or bike rack. The Seat-Lock system (ORTLIEB patent) clips directly onto steel or titanium saddle rails — no tools, no fuss — and releases just as quickly when you reach your destination. At 7.5 litres (42 × 22 × 16 cm) and 490 g, it carries enough for a full day out or a lightweight multi-day trip. The compression valve with strap handle and 5 external compression straps let you cinch the bag down tightly when it's not fully loaded, preventing unwanted movement. An external bungee cord gives you quick access to gear you want to reach without opening the bag. The roll-top closure combined with PU-coated nylon (PS21R, PS33) delivers IP64 protection — dust-tight and splash-proof from all directions. A reinforced rigid base protects your belongings from impacts, and the underside protection plate doubles as a mudguard, keeping road spray off your kit. The integrated reflector and daisy chain make it straightforward to attach a rear light for low-light riding. Works with dropper posts between 22 and 35 mm via the included adapter (4.3 cm wide), with a maximum load of 3 kg. Not compatible with carbon rails or non-standard saddle designs. Made in Germany, 5-year warranty.
