Well, a week ago or so I posted a message about a crackling bottom bracket. Well I got a "tune-up" at the bike shop I bought the bike from, and they replaced it with a brand new FSA BB that is supposedly better than my other Truvativ BB. But on my old one, there was a little seal that screwed onto the bottom bracket on my frame, and with this FSA one it just goes right in. I asked about this and they said that FSA doesn't come with those, but could I put the Truvativ one back on there?? Because it looks like dirt will get in there, even though it's sealed.. I don't want dirt all in there. I'll post some pictures for better understanding once my camera charges.
