1989 (?) Yeti FRO

[mkozaczek]

You mic'd it and measures 26.6mm?

Steel tubes have a tolerance so, it happens that some are a bit over that's normal.

My 87 Valkyrie was meant for a 27.2 post and there is no way it will accept one. I know of several others like that.

Regardless, I'll start tracking the seatpost size in my DB.

Seatpost says 26.6.

Measuring the ID of seattube gives me various results: 26.8 right at the top, 26.6 3cm down the tube.

Right... I have a FRO with a 26.6 post, but it's a loose fit in the ST.

I think that FROs were all designed as 26.8 but dimensional tolerance and things like that may mean some ended up slightly undersized.

In this catalogue, probably the first one from 1986/87, it is stated that the seattube is 26.6mm.

I know things have gone off at a bit of a tangent here but I find this thread compulsive lunchtime reading
sure I like looking at pictures of build progress, but this is interesting

Remember, there are two pics of the bike with wheels on p5!

Well, I'll be a monkey's uncle. I'll check 309 when I get home, but I swear they were all 26.8 and only the 85s was 26.6

Good detective work.

Looking great .

Martin, I have a new theory:

Frame is XR 335, it is one of the first with the 2nd gen. Yetiman (making it 1987) and one of the first with oval top tube. At a later point, the stem was added. The stem seems to be custom, as the shaft is made of Aluminium, just like the A-TAC ones. Also, the paint of the stem seems perfect wheres forks and frame have been touched up a lot. In addition, the stem, being cromo, should have been labelled "Yeti". However, it was labelled "FTW" (aluminium models)

Can you try to fit a 26.8 post and report back if it fits?

FWIW 309 takes a 26.8, but the owner of 314 says it takes a 26.6.

The red Yeti is decidedly 26.6 and will not accept a 26.8
