Handlebar Mount Not Included. Made of durable and waterproof polyester fabric, the ORTLIEB Ultimate Six Classic is a compact handlebar bag that plays a key role in the gear management plan of all bike touring enthusiasts. Depending on the model, the Ultimate Six Classic offers a 5.7 or 8.5-liter payload and ample space for your valuables and the things you want to have at the ready on your tour. The transparent and rainproof flap compartment that comes with the five-liter model offers 21 x 12 cm interior space for the convenient stowage of smartphones, GPS devices and maps. And you can naturally operate your touchscreen device through the transparent cover. The two larger models enable the use of different inserts in case you want to securely stow any special gear such as your high-performance camera while you're underway. All of the handlebar bags come with a detachable shoulder strap, a reflector and a zippered inside pocket. All Ultimate Six models are compatible with all ORTLIEB mounting sets, as well as Rixen & Kaul Klickfix mounting systems.
