Hello, looking to build my 1st chinese carbon 29er and I am confused about the bottom bracket. Am I better to go with BSA or BB30? I am looking to use most of the parts of my current build so I want to make sure I choose correctly. I currently have FSA MegaEXO Sealed external bearing, 68mm. I am looking to go with Flyxii Fr-202 which comes with 73mm BSA or BB30.

Which would be better for me? Thanks in advance.
