Best bike/wheels combo to be drafted

I am looking for the best bike/wheels combo to provide the maximum draft to to my fellow companions. I don’t mind to be slower, i just want people behind me getting the most of the draft. Do all bikes provide the same draft?

It’s not the bike. If its not too late, eat your crusts and grow tall, then eat some more and grow broad. The biggest draft source is the rider. If Zwift’s model is accurate, put your tallest and heaviest rider in front.


Does the draft we create or provide change with our CDA?
I know our speed changes but I thought on Zwift, draft is draft.

I’m not sure anyone knows the answer to that, has it ever truly been disclosed how the draft is calculated?

Thank you all for the replies.

I did say “If”.
