ORTLIEB&';s frame bag with roll closure helps you start off your bike packing adventure well-prepared. Thanks to the waterproof roll closure -which is closed by three silicone rings- paired with the proven nylon fabric, your luggage inside the bag stays absolutely dry even in the most adverse conditions. The Frame-Pack RC is ideal for storing heavy luggage, such as tools or food, centrally on the bike. This maintains a low center of gravity so that the trail fun remains high even when fully loaded. The roll closure and its large opening allow easy access and easy packing of the bag. The assembly within the frame triangle is done with strong and robust Velcro fasteners. The specific positioning of the Velcro straps along the circumference of the bag enables individual adjustment to the dimensions of your bike. The Frame Pack RC is available in two sizes -4 and 6 liters - and suitable for mounting on carbon frames. The bag is PVC-free and sustainably made in Germany.
