Specialized Como - 2017 - pannier rack

[Bev_dev]

Hey folks, I want to fit a rack on the back of my 2017 Como, so that I can add panniers. Can I fit any rack, ie Decathlon, or do I need to buy a special Specialized one? Thank you!

Sorry no one answered your question. Could you please post clear pictures of the rear triangle of your Como (including the rear axle) and of the back of the seat-tube?
Como e-bikes were available in several versions, therefore giving the answer is only possible when photos can be seen.
