The waterproof welded Trailsaddle Compact L bicycle saddle bag offers a reliable solution for carefree bikepacking with its large capacity of ten liters, aerodynamic shape, and secure KLICKfix® quick attachment. The mounting bracket of the attachment system is installed under the saddle and allows for quick installation and easy removal with a click via the adapter on the saddle bag. A sturdy Velcro strap additionally secures the saddle bag to the seat tube. The waterproof roll closure and a vent valve enable optimal compression of the contents. A long stabilization strap attached to the top compresses and secures the contents flexibly after rolling up with a hook buckle in a webbing strip, where a flashing light or other small items can also be attached. If the strap is not needed, it can simply be looped out. A flexible cord spider on the top of the saddle bag keeps gloves or a rain jacket quickly accessible. The Trailsaddle Compact L is best combined with the Trailfront Compact handlebar bag to fully secure the touring luggage to the bike - completely without a rack.
