Hollowtech II question.
Hello, mechanics, can I ask a mechanical-type question here? 😁😉
My Soma Saga has had a Shimano FC-6603 triple crank on it, since before I bought it, around a year ago. The BB is worn out, and I bought a SM-BB52 (Deore for a MTB) for a good price on craigslist. Is this BB compatible? I strongly suspect it is, but thought I'd ask here, before taking everything apart. 🙄😉 Thanks much for any help. 🙂 |
Why not go to the Shimano website, look up your crank and find out what BB it uses ?

Yes. Use your old plastic sleeve, the mtb Hollowtech bb sleeve that comes with the bb you purchased will be too long, designed for a 73mm shell instead of the 68mm shell on your frame. No biggie.
I have the proper Park tool, and a 28t ring that "might" fit where the 30t ring is now. Both were cheap, so I took a chance on the chainring. 😉 |

Thanks much, just wanted to hear it from someone with some experience. 🙂 I've messed with square tapers quite a bit, off & on, but this was my first encounter with Hollowtech II.

If I were just replacing it with the same BB, wouldn't it be easier to just look at what's on there now? 🙄
Thanks for nothing. 👎 That BB is probably fine I can't see why it won't unless it is the wrong size like for a fat bike or something but you would probably know that. |

It was actually good advice, Shimano does a lot of compatibility charts to help us all out.
I apologize if I was out of line, and thanks again, all, for the help. ✌️ |

I'm still touring, and on a phone,
Too many turn up here and don’t wish to contribute to their solution, you got rolled in with those. As with all (most) bike shops, those touring get priority Barry |
