Depending on your bike, they may be sealed. If they are sealed, don't grease them (you can't). The only excpetion would be if you install new bearings, put a little grease on the metal to metal contact areas.

If they are not sealed, grease them whenever they feel shitty. Take them apart, clean everything really well with brake cleaner or alcohol, and regrease them.

I use Park grease, but you can get away with any lithium grease. Avoid high temp grease because it's not very good at low temps.

You certainly can grease sealed bearings, just they don't often need regreased and more often than not, it's better to just replace them anyway. I've regreased countless ones. Just pop the seal off, clean it out, then put a bit of grease in there and pop the seal back on


If they're sealed bearings, you really shouldn't have to touch them unless they start feeling sluggish or making noises. If they're unsealed, I'd probably regrease them like twice a year or when they start feeling sluggish, making noises, etc. It's always good to adjust them every now and then, helps them last much longer that way.




Most any grease will do, Park Tools is commonly used by a lot of shops. I just use random all purpose grease from Wal-Mart

Yeah, you're right. They would never let me do that at work, and I get stuck in that mindset sometimes.

But, I do think it would be pretty difficult to remove and replace the seal without damaging it, and new BB bearings are pretty cheap. Realistically, if you did damage the seal, you could flip the bearing around so the damaged seal is toward the inside of the BB, but than I've also had issues removing BB bearings without damaging the seal.

You need a good set of picks usually to do it well. I've been running the same BB for around 7 years now because I do that around every year or so.

Yeah removing hub bearing ones are a pain in the ass. I usually use a razor or a dental pick we have at the shop but even then it's risky so I only do it if it seems necessary. Bottom brackets are a lot easier and like you said you can just flip em around sometimes haha
