I think so too . And there made the same way , each bag one Velcro strap up one Velcro strap down the two mirror each other and hang right over the rack the straps with their adjoining clips must attach somehow I may have to play with it ( the Germans are really good engineers). I will contact the company and ask them perhaps they have an archive of directions for this particular bag which seems to me to be quite old. If I can find the identical mate, that would be interesting. My old French bike is a motobecane grand touring jubilee 1978 with the very good but common rear rack a "Pletcher " . It's got a spring loaded section. Not entirely sure how I may use this pannier , as a single. Maybe I can wrap the straps underneath the spring loaded section or tie it on somehow . I don't feel like modifying the bag if I can avoid it another one may show up somewhere.
