Greetings.
From what i can see, those panniers are monokey (not monokey side) and the kappa site doesn't show any rack other than the monokey side rack, for our model.
Therefore my advice is to contact kappa, directly from their site, asking which rack is appropriate for the Crossrunner 2015.
I have contacted them because of the handguards and they have replyed in 1 or 2 days.
