Ortlieb Seat-Pack QR

Quick release. Full send. No compromise.

The your go-to saddle bag for off-road epics, gravel missions, and ultralight bikepacking. Built around the clever Seat-Lock quick-release system, this waterproof 13L bag mounts fast, stays rock-solid over rough terrain, and pops off just as easily when you reach camp. No wobble, no fuss—just dialled performance from the first ride.

It’s tough as nails with abrasion-resistant nylon and reinforced internals. Compression straps, an air valve, and elastic bungees keep your gear compact and secure, while a built-in underside protection plate guards against tyre rub and doubles as a mudguard.

And yes—it even plays nice with dropper posts (just 4.3 cm of clearance needed). Just make sure to check saddle compatibility before you commit.
