30.9 is a thing

Cheers is that on newer frames

It's a common spesh size
Lots of aluminium.

It's hard to accurately measure inside diameter - the top section of the tube is often distorted by the wrong post, and the welds often mean its not regular.

Best test is to try to fit the post.
The right one feels good.

As stupid as it sounds I never even thought of that I think I got 31.6 ringle and I thought I had a 30 ringle but finding the sizes it's probably a 29.4 ringle the callipers I have I only just noticed there a mm out so I went through measuring everything and it's all wrong plus they don't go downt to 0.1 etc so pics useless haha
