Hi

I'm after a new seatpost for a 1994 lava dome.

Can anyone tell me the correct diameter please ?

I'm looking for a new seat post but can't measure up my current bike as I'm away from home for the next few weeks.

I'd got 27.00 mm in mind but looking through the forums people are talking of 26.8.

Does anyone have a definitive answer ?

Cheers

James
 
Generally they are 27.0mm. However, the size depends on how much the seat tube ovalised during welding. One with little distortion will take a 27.2 (like mine) and I imagine that some occasionally take a 26.8.

I'm sorry I cannot be more specific than that.
