The BB Infinite bottom bracket PF92 DUB also uses 30 mm bearings and a polymer sleeve.

I realised this when I ordered one for my XX1 DUB crank and one for my Canecreek eeWings crank. Same shell, same bearings but the DUB version had the inserts.
They also sell the inserts as replacement parts: [https://www.bbinfinite.com/products/dub-bearing-inserts-service-part-pair?variant=21140415414331](https://www.bbinfinite.com/products/dub-bearing-inserts-service-part-pair?variant=21140415414331)
And I can attest that their quality is insanely high (ie let's aim for perfect and deliver that to the customer).
They also have excellent customer service which is a bonus.
