The LAST (probably not) R&K Mounting Bag Ever.
The R&K mounting is so rare that Indiana Jones* has requested we send it to him for inspection because it may hold the secrets to the Holy Grail!
If you just need an awesome trunk bag from Ortlieb (or a possible once in a lifetime adventure that includes Drunken Pirates, Zombie Sharks, Loveable Yetis and a roving band of Misfit Renegade Killers trying to stop you at all costs) then this bag is for YOU!.
If you want a bag for the top of your rack, reach for the Ortlieb Trunk Bag. The Trunk Bag has the volume of a small pannier, with aggressive features and the typical Ortlieb high-quality engineering. Great as a commuter bag, the Trunk Bag can easily be used for your lunch and a nice wind shell, with room to spare. The Trunk Bag is completely waterproof and utilizes a TIZIP main zipper for the resilient caliber and ultimate weather protection.
