1992 Stumpjumper Pro seatpost diameter? Help please.

[wordnumb]

Morning all. Would anybody know the precise diameter seatpost required for a '92 Stumpy Pro (light blue/aquamarine)?
I think it may be different to the '92 Comp frame, one of which I accidentally customised yesterday on a greasy supermarket car park corner.

I've seen 27mm mentioned but I reckon it's more like 26.something. I've searched the forum and catalogue scans but if anyone knows for sure it would be appreciated.

Ta muchly.

According to @boy"O"boy post the seat post diameter is 27mm

Yeah I saw that. The 27mm post I bought for it wouldn't fit. Gave that post to a mate who needed a 27mm post and he's still using it. So I don't think it's 27mm.

Pretty sure it's going to be 26.8 ... but confirmation would be really helpful.

Still not what you're asking, but my 92 Comp is 26.8

26.8 on 92 s works im sure

Cool, I'll take that as gospel. Ta muchly.

I know my '94 Stumpjumper takes a 26.8, but can't recall what my '93 Stumpjumper FS takes.
Sounds like 26.8 will be a good bet.

To close the thread, the 26.8 post fits perfect.
Now I just need to transfer everything over from the damaged Comp.
