MegaExo BB Help

My FSA MegaExo bottom bracket is dead after a long fight with friction. I crashed on it a while ago and ever since then it’s felt a little crunchy. It’s finally making some horrendous clicking and pinging sounds, so it’s time to be replaced.

From FSA’s website I’ve determined that the part number I need is BB-6000. That’s the bottom bracket for a 68mm shell, English thread, for the Gossamer crank.

I fired off an e-mail to the LBS and was told that they BB they stock, while not BB-6000, will work for any English shell. FSA lists several different part numbers, one for each crank they offer (Gossamer, SLK, etc).

So who’s right here? Should I trust the LBS and try the “universal” FSA BB, or should I just order the specific part for the bike? Anyone have any experience with this?

Thanks!

The bb your LBS has will work just fine. English threading for bottom brackets is universal.

Right, the threading is universal, but FSA has multiple BBs for English threading, based on whether the crank is a double, a triple, Gossamer, SLK, etc. Do you think they’re all the same?

Maybe for internal bbs, but not for external bearing ones.

Thank ya.
