Diamondback Ascent 1995? seatpost size HELP

[JoanFontcuberta]

I recently got a Diamondback Ascent, perhaps year is 1995, not sure tho. When I bought the bike it came with a 26.6 seatpost. Can anyone confirm the right seatpost size for this frame? I will check again with a caliper tonight. Cheers

My 1994 Axis takes a 27.0 - that might be the same. What's the frame number please? Will confirm year.

26.4 I reckon. Axis was OX tubing, more oversized than run of the mill frames lower down in the lineup.
Why do you doubt the size of post that came with it?

Only if I tight the seat clamp very tightly, above the average, the seatpost doesn’t go down. Also the previous owner told me that the seatpost was undersized when I bought the bike from someone else
