I don’t disagree with you there. I’m not the biggest fan of SRAM, but I appreciate that they never put their name to a PF92 to BB30 bearing.
I wasn’t trying to say you’re wrong really. Just pointing out that sometimes it’s hard to predict the consequences of industry trends or design decisions.
My personal opinion is that press-fit exposes manufacturing flaws that would otherwise be masked. When a company fails to hold appropriate tolerance, instead of just getting a molasses crank you also get a creak. But when made properly a PF interface can give significantly better bearing alignment than a threaded interface. Instead of complaining about pressfit I wish people would direct their ire to the companies taking QC shortcuts refusing to warranty defective products because they know most people don’t have the tools to prove it.
So yeah, I can see why we should get BSA for budget rigs. But the fact press fit can’t be executed reliably on frames costing multiple thousands is appalling.
