I would first contact Canyon since it should not be sold with a brake issue like that. Could be some mistake was made during assembly such as too-thick spacers (if there are any) or who knows but they may be aware of the issue. grumpus' idea to trim the pads is a good one and I would even say a good long-term solution if you get no satisfaction from Canyon. Maybe aftermarket pads will fit better or a different rotor, but you should not have to shell out extra $$ to fix this IMO.
