Originally in a Factor O2 bike that I got in 2020.  I removed it and went with a native 24mm for Shimano.  Bearings spin smooth like new.  Most of the marks on the bb came from being in a parts drawer for 4 years.   If you want to use it with Shimano you can.  You just need to get the shims/bushings (Wheels MFG makes them)
