We've seen some crazy BB30 bearing removal mishaps over the years, from a bearing cocked in a bore so bad that we had to cut the race with a Dremel tool to avoid further damage, to a newbie mechanic who, right in front of us, missed his hammer swing and hit the Litespeed CR1 he was working on, cracking the frame. Needless to say, don't do that. ATTENTION: The bike we are working on here is a team bike that gets ridden hard. It's not a delicate flower. If you like to massage your bike with a baby diaper after every ride, that's cool, and so we recommend either removing the chain or wrapping it in a rag before doing this procedure. This way it's not flopping and banging all over your paint while you work. Could it scratch your paint? Yeah, it can, so watch it.
BB30 is extremely popular still to this day and we get a lot of questions about how to remove bb30 bearings from a frame so there's a lot of cool tools out there. Come over here and take a look at this one this tool right here you can see how it interfaces with the bearing on the back side. See that in order to push it out it ends up hitting the inner race to knock it out now you don't need a fancy tool like that. Really all you need is this and of course this and what you want to do is you want to do the same thing you're going to go ahead and you're going to get on the back of the bearing just like that and you're going to be able to hit that inner race and you're going to try to walk it out step by step because what you don't want to do is you don't want to you don't want to hit it just on one part it like that because it actually get cocked in the bore and could cause some damage so you just want to walk it out so we just want to go ahead and we want to look inside to make sure we're hitting that inner race if you want to look inside here right there I'll go ahead and shine a light in there you can see I'm just hitting that inner race right there and I want to look in there specifically because I want to make sure there's not like a Di2 wire or something hanging down and I went ahead and pinch it between here and in a race and when I hit it it's going to cut it we don't want to do that so we want to just go ahead and we're going to go ahead and knock this bad boy out there like that boom moved a little bit moved a little bit move a little bit and then move a little bit now you can see you can see it's starting to walk out see that so if you just keep right there i'll show you how it continues to come out just like that just like that just like that and then finally it comes out okay seems a little violent it's not it's no big deal the biggest thing is to walk it out progressively incrementally step by step rather than try to get it all at once all right I'm going to show you guys how to get the snap ring out because now that we have the bearing out we have to get the snap ring out that acts as the bearing backstop so come on and take a look here and I'm going to show you this is the snap ring right here you see it's actually loose because it's inside of this there's a groove down here so this is a smallie style ring so you take a flat tip screwdriver and just get it up underneath here you see how i can lever that out and push i use my finger to push from the back side if you think you're just going to do this number a lot of course it wants to do it trust me a lot of times this thing just does not want to come out of here so you want to be able to get it up and then push it like that to go ahead and get it out and now the bore is clear so we can get the bottom bracket in there easy as can be
