The Topeak Back Loader is a 10 litre bike bag designed to help bike packers, tourers & long-distance commuters carry luggage safely & securely. Weighing just 480 grams, this bag is relatively lightweight & without the need for a rear rack, dramatically reduces total system weight. To minimize bulk even further, this bag also comes fitted with an air release system. Thanks to the new saddle mount system & compression straps, the Back Loader can be mounted & removed in seconds. in addition, as a direct result of this new design, the pendulum effect has also been significantly reduced, offering you security & peace of mind throughout your ride. With a roll-top closure system & a waterproof inner bag lining, the Back Loader protects the contents from even the most torrential downpours. Although many bike packing bags have a habit of blocking lights, this bag comes with a dedicated clip for rear lights, so you can always remain safe & seen.
