A quick Google search suggests it's a BB386Evo. Do you see that number, or maybe just a "386" stamped anywhere on it?

Further confirmation:

https://machiine.com/2017/the-wilier-triestina-zero-9/

https://www.racycles.com/product/detail/5707

That last link makes it sound like it's a custom BB:

"The bottom bracket standard is the Wilier co-designed BB386EVO, designed for 30mm diameter thru-axles and 86mm wide bottom bracket shells"

    It appears you need the sort of BB that mates with the BB386EVO frame standard but "adapts" it to 24mm spindles, which is different from just a BB386EVO BB. Dec 10, 2018 at 22:40

    I pine for the days of just a couple of common BB standards.
