Zero setback posts were created for MTBs, and are often misused on road bikes that are designed to be paired with setback posts. Make sure you have appropriate setback to your position.
Thanks for replying.
So, what you say is that even if i place the saddle in identical position and that exactly from bottom bracket and stem to saddle nose I will have to push it backwards on the straight seat post to get similar position as with the 20mm setback seat post?
