    Can't you just measure it?

    Or stick the post in. If it doesn't fit, it's the wrong size.

    Not miles out, but far enough to be the wrong size.
    You need to either buy the correct diameter seat post or a shim to allow you use your current post.

    0.7 of a mm not a huge difference .

    It's big enough of a difference not to fit, Ask an On One owner... You'll not get the clamping force required to stop it from slipping. Shims are available, USE make them, but if not then new post time.

    In terms of the tolerance in the seat tube internal diameter it is a huge difference. As Tom Howard says, you won't be able to clamp the seat post in place. You could always do the clamp up so tight that it crushes the seat post so the dropper function no longer works or just buy one of THESE.
