Ortlieb Saddle-bag

"The Ortlieb saddle bag is the perfect solution for all cyclists who need practical storage space on their tours. Whether cycling, mountain biking or on a road bike, this waterproof bag offers optimum protection for your equipment. With a volume of 4 liters, it offers almost as much space as a small backpack and is therefore ideal for longer tours or as a supplement to other luggage. The compressible roll-top closure and side buckles ensure that everything is stowed securely and wobble-free, while quick access is guaranteed"
"The innovative adapter system enables easy attachment directly to the saddle, while the adjustable click fastener allows quick attachment and removal. The compatibility of the click fastener with fork models is particularly practical, which facilitates flexible use on different bikes. A Velcro strap on the saddle support provides additional stability and prevents the bag from swinging unwantedly while riding. In addition, the large saddle bag almost replaces the rear mudguard and protects you from splashing water."
"Please note that the bag should not be attached to carbon-saddle rails and carbon-saddles in order to avoid material breakage and the associated risk of injury. The maximum load of 2 kg should not be exceeded in order to ensure the safety and durability of the bag. This saddle bag is an indispensable companion for anyone who values quality and functionalityu00e4t."
