"Tipped everything I have out and no sign of a 26.8 ..... Miffed where its gone buddy sorry"
Could of sworn 1 came with a Zeus I bought a while back. The 27.0 is on a Raleigh (silly of me to think it had a 26.eight) Got 7 seatposts and not 1 is the 26.8
Really don't mind taking the 27.0 down 0.2mm to get her to a 26.8, it's only a 5 minute job on the lathe
So sorry for the false alarm, feeling a right twit now (remove the w if you like
Best of luck DB, and honestly "It's no hassle to take 0.2mm off a 27.0". Later buddy, yours Laz.
PS: Isn't it funny how when you tip an entire collection of "Stuff" out on the floor it a) takes up an entire room, & b) has parts in but you have no idea where they came from .... that cost a fortune
