Thank you very much!Hi there
I assume you mean the part attached to the front half of the frame ?
I have 2
Both measure 36mm outside diameter 3mm wall and 30mm inside diameter.
I also have a head tube that measures 34mm outside diameter 2mm wall and 30mm inside diameter.
Hope that helps Paul
That's okay, I appreciate you trying, and I hope you feel better soon.Whilst I have ongoing health problems i can only reach 2 of my stash , I suspected I have another 3 or 4 but can't get to them.
I remember I have one with bearings in it [ I know which box it is sat in , no idea where the box is currently ] so cannot measure that sorry.
