I think I have a Zipp Service Course knocking about somewhere, I think it's 27.2mm. The layback is 20mm though if that suits? If I can find it you are welcome to it FOC. Give me a day or so to try and dig it out and check it is the right size!

What’s the correct term for a ‘Layback seatpost ? Trying to buy one to gain a bit of space on one of my bikes - 99% of what I’m finding are for 1980’s BMX’s……

Bike not with me. Pretty sure it’s a 27.2mm post though. And I’d like to gain upto 1” of rearward offset.

'Setback' or 'offset' are most commonly used.

‘Setback’ appears to be the term. As opposed to layback…..which is traditionally more BMX terminology….
