Man, what a rack ....

[ingobohn_imp]

Unfortunately, I do not have a picture. I only remember that also on a 2 day ride with my wife I put the 30 L roll on the rack. I used 2 Rock Straps crosswise, one end at the rear bolt of the side rail (where also the Fehling rack is mounted) and the other end at the "opposite" side of the rack itself. I tightened the straps strongly.
The 50 L roll is just too large for the rack, but mainly because it sticks out laterally just too much (instable?).
When I ride alone and drive on the Autobahn, I but the roll (30 L or 50 L) over the rear seat and over the rack (for "high speed'ability").
