    Seat Post Size 27mm or 27.2mm?

    I am looking for a seat post. My old one looks like a 27mm, but I see more 27.2mm in the market than 27mm? Can I put a 27.2mm in a 27mm frame?

    Both my bike take 27mm. I wish they could have speced a 27.2, but no, you need to use 27.0 in that frame.

    I've done this before - - on accident - - and I don't recommend it. The frame was sized for a 27.0. I bought a 27.2 and proceeded to have to "turn" it down rotating it on my belt sander and with emery cloth. What I wouldn't have given for access to a nice little South Bend lathe! What a thankless chore.

    The trouble with this is I also removed the anodizing (yes, even when it's raw color, it has been anodized); so now a particularly unattractive, dark, discolored almost-silver post. Hunt down a 27.0 and you'll be happier.

    I'll trade you my 27.0 for your 27.2. Mine's nothing special at all though.

    Sorry, I can't trade. I made a big mistake and cut my post. That is the reason why I need to buy a new one now. I know and I will never cut any seat post again.

    Thanks, I guess I need to take my bike to bike shop to find out.

    If you follow this advice and your frame is still underwarranty. Your frame will no longer be under warranty. In cases like this Dremel tools are a very bad thing.
