Kona seatpost sizes.

[Spanky22b]

I've just got a 91 Lavadome which has been resprayed and also have a 92 Lavadome so i tried the seatpost which is 26.4mm from the 92 bike and it doesn't fit. Can anyone with a 91 Lavadome confirm it takes a 26.2mm seatpost.

Check the seat tube for ovality, especially by nudging the clamping area open a little. Also measure the post - it should indeed be 26.4. There can be some alarming discrepancies to what is nominal though, often 0.1mm.

Done what you said and it fits perfect
Any idea what size a 91 Cindercones seatpost should be?

Most years Lava Dome and Cinder Cone shared the same frame, so I would again start with 26.4.

Hi all, Just wondering if anyone could advise on front mech type and size required for a 1991 Kona Lava Dome? Also, which size seat post do these use? Many Thanks! Chris

Probably it's 26.6 nominal with no heat distortion from welding.
