The waterproof bicycle bag keeps travel luggage safe from moisture intrusion due to rain or splashes. Thanks to the 2-way roll-top closure, the volume can be expanded by an additional 5 liters. The newly developed BagFix mounting system ensures maximum freedom of movement, as the load is 100% on the rear wheel and not on the biker's back. The bag can be easily removed from the rack with one hand and used as a shoulder bag. This makes its use nearly limitless.
