    How much seat post extended is too much seat post

    When do you look at a seat post and realize that it is too long? Road Bikes.

    There is usually a line on the post that tells you the how much post you can have above the seat collar or how little you have still in the bike.

    if not marked...

    As already noted, the post shold have markings for max. height. If it doesn't then one rule of thumb is that the end of the post should be below the bottom edge of the top tube.

    Carbon posts are usually marked at 6-7cm from the end.

    I guess...

    what the OP wanted is how much cm of seatpost should be sticking out on a traditional road bike not considering the markings( could be mtb post). i'm curious too.

    Well I recall seeing some pictures of a couple in the thread called "Show us your Taiwan and Chinese..." (something like that).

    Too much seatpost = undersized bike. Perhaps that's what the OP is after.

    That depends on how much drop you can take, pros ride ridiculously small frames to be able to get the desired drop.

    Clarification

    Now we are getting to what I am after. Clarification: when do I look at how much the seat post is extended and realized that my bike is undersized?

    My race bike

    That depends. I have a XL Fastback comp with a 410mm Thomson mtb seatpost. 220mm of seatpost is exposed. Others have told me I have a scary seatpost. I dunno. I like it.

    Don't forget that many frames these days have a sloping top tube. Those frames will expose more seat tube than a traditional one. It's better to look at the vertical distance or drop between the saddle and the handlebar.
