Cannondale Systemsix Hi-Mod Bottom bracket

Hi,

Could you help me to understand how I should manage the replacyof my BB ?
A lot of cracks since 3 weeks and I would like to replace (or at least remove, clean, grease) my BB but I have trouble to know wich standard is used and which tool I should buy in this purpose.

It’s a Systemsix Hi Mod from 2021 with Sram Rival/Force (custom build that I bought used).

I understood that it is BB30 standard and that there is two different for Cannondale, BB30A and BB40-83 AI. The width is 73mm so it’s the BB30A that is used.

I’m not sure how to manage the removal ? If I understood well there is no threads on it (it’s a press fit BB) but strangely I have the feeling that with the right tool I could unscrew it. I put you some photos to see the BB from outside.

Any ideas ?
