WTD - PF30A to Shimano bottom bracket

I picked up a Cannondale SystemSix 2019 recently and I'm wanting to move to a Shimano Hollowtech II crankset, mostly for the ease of swapping chainrings about, rather than the all-in-one rings/cranks setup that it currently has.

Thus I'm looking for a "good value" PF30A -> Shimano 24mm bottom bracket. I'm not looking for adapters.

If anyone has got a spare lying around, please get in touch with a price inc. P&P.

Also, if anyone has tried this and thinks I should not do this, please get in touch also!

Thanks :smile:
