I was wondering if anyone could help me with finding out which size seat post to buy. I have a 2006 Orbea Onix. This is my first time using this forum or any forum for that matter (I know embarrassing). Hope it proves useful...

    If it's a round seatpost (I don't know the bike off the top of my head) - take the old post out and it should be stamped somewhere around the minimum insertion mark. Would guess it's either 27.2 or 31.6 as they're the most common outside of specialized.

    I pulled out the seat post and it didn't say anything. I'm also not looking to buy any sort of tool just to find this one time measurement...

    You don't own a tape measure? Really?

    I was foolish enough to believe that there was some Bike guru who knew every bike manufacturers measurements off the top of his head.

    there will be a marking on it unless it has been cut down.

    and you need to know to the nearest 0.1mm

    For info the Sheldon Brown site is the most comprehensive site for bicycle related technical information on the web.

    Despite the unfortunate demise of the late and great Sheldon the site is kept up to date by various contributors

    In the absence of a ruler/tape measure/spec sheet then why not just take the seatpost into a bikeshop and compare them? This could also be the start of a good relationship with your LBS which you will definitely need if you are adverse to buying tools...
