The rear rack uses a secure three-point fixing structure that distributes weight evenly and keeps the waterproof compression bag firmly in place. Even on rough roads or bumpy trails, your gear stays stable and wobble-free.
Comes with a premium waterproof compression bag made from durable fabric with fully taped seams. It effectively protects your gear from rain, mud, and splashes, keeping your belongings dry during unpredictable weather.
Extended side and rear straps allow flexible adjustment to suit different packing setups. Designed to carry tail bags up to 12L capacity and 54 cm in length, with quick-release buckles for fast installation and removal.
The rack weighs 284g and the compression bag 120g, offering strong support without adding unnecessary weight. The PP board rack is easy to clean and resistant to dirt and moisture, while protective pads help prevent scratches on your bike frame.
Compatible with most road bikes and mountain bikes (requires at least 12 cm of saddle post clearance). A waterproof side zipper on the bag allows quick access to gear and improves airflow during compression—ideal for bikepacking, commuting, and touring.
