    I can't find any reference to the seat post size. However, the 2017 Dirt-E+ 0 came with an externally cabled Giant Contact SL Switch Trail dropper post and that was only available in 30.9mm diameter.
    If you remove your seat post the size will be etched/printed on it near the bottom.

    This link should help you decide which dimensions are important for your bike. It's not just the seat post diameter and the travel that you have to consider.

    The web page is in French, but if you wait a short while it should auto-translate. Or use Google Translate. The page is a few years old so it may not have your exact post on it, but by reading and understanding what it's telling you, you will know what to look for.

    Giant bikes are pretty much 100% 30.9mm, logic says just use a Giant dropper. The local Giant dealer will know what drop it will take.
