I had two frames with PF30. The Niner used an eccentric to adjust chain tension and it was pretty awful. Creaking, slipping, it took a lot of experimenting to quiet it down. Also didn’t love the way the crank position / bb-height changed.
The other had sliders so the PF30 was just a BB. It was dead silent with nothing needed but some copper anti-seize (frame was titanium). But there still wasn’t any reason I could think of that BSA wouldn’t be better.
It’s nice that most the industry is drifting back to settled tech with BSA.
