    Easton Seat post

    What, if any, are the differences between an Easton EA50 seatpost for a road bike and the one for a mountain bike? They are the same diameter, and I am wondering if I can use the "mountain" bike post on my road bike?

    The mountain bike post is longer.

    If the diameter is the same, you can use either without a problem.

    Not a universal rule, but if you "show" a lot of post, so that it is close to the max line, ride a particularly large or a compact frame, some folks recommend you use the "mountain" post, so that the bottom of the seatpost when installed is fully south of the bottom of the intersection of the seat tube and top tube.

    Of course, the mountain post weighs more.

    They are identical except for length. See the thread on cutting a carbon seatpost for a discussion on shortening MTB seatposts if they are significantly longer than you need.

    I have a Easton mtb post on my road bike. I broke out the tubing cutters and cut it down to size.
