The Rack Bag 10 KF attaches to the luggage rack using the UniKlip 2 Klickfix system. The bottom of the bag features four "grooves" that latch onto the racks tubes. The bag, which sits on top of the rack, helps keep the weight of the gear aligned with the bike's centerline, unlike using a single side bag, which can cause an uneven load. The carrying straps allow the bag to be carried like a backpack. The Rack Bag 10 KF is a good choice for commuting and bike touring when you dont need a lot of space. - Includes small zippered interior pockets - Side pockets - Elastic band on top, perfect for tucking in a rain jacket - Rain cover included. Its recommended to apply protective tape (such as electrical tape) to the contact points of the luggage rack to prevent the bag from wearing down the racks surface paint.
