Prepare for bikepacking expeditions with the ORTLIEB Seat-Pack, a critical component for any serious touring setup. This waterproof pack attaches securely to your seat stem via robust Velcro straps while doubling as a rear fender. Available in two capacities—8-16.5L or 7-11L—the volume adjusts precisely through side roll closures, while the integrated compression valve optimizes packing density for soft gear. The 16.5L variant features tactical elastic drawstrings for quick-access items and requires only 15cm of seat stem clearance. Versatile across hybrid, mountain, road, and e-MTB platforms, this technical pack transitions seamlessly to day-trip use when off the bike.
The ORTLIEB SEAT-PACK F9902 delivers professional-grade bikepacking storage with technical precision. Requiring a mere six centimeters of seat stem clearance, this compact model excels on smaller frame geometries, full suspension systems, and adjustable seat posts where space is at a premium. Engineered with waterproof construction and secure Velcro mounting, it maintains ORTLIEB's signature volume adjustability while offering optimal weight distribution for technical riding. The integrated compression system ensures load stability across varied terrain, making this the definitive choice for riders requiring performance storage solutions without compromising bike handling characteristics.
