How do I check and maintain my bike's bottom bracket?



So, we're talking about bottom bracket maintenance, right? Everyone's all about those press-fit and BB30 systems, but are we just glossing over the actual checks? What's the real process for inspecting those bearings?

Do folks even know how to spot wear before it goes south? I mean, it’s not just about cleaning; it's about understanding the wear patterns and knowing when to replace. What’s the threshold for replacement? Is it just a gut feeling or is there a method to it?

And the tools—are they really necessary or just a way to drain wallets? I’m curious how many riders actually invest in the right gear versus just winging it.
