Old Suntour SUPERBE BB Replacement Question...
Hi Y'all-
I want to buy a replacement BB for my old Superbe Pro crankset... I just need to sure that what I am buying will be compatible.
old BB: 68mm / 109mm spindle / double
Is there a specific make/ model that I need to find, or will almost any other BB with the same specs work?
Any recommendations?
Big thanks in advance... Dick

As long as the new BB has the same dimensions (68mm shell width and 109mm spindle) has a square tapered spindle (the Superbe has a square taper, right?), and the same type threads as the frame, it will work.

Thanks for the info...
The cranks have become fairly loose and a couple of different local bike mechanics told me that the BB should be replaced. I must admit, although I've been an avid rider for years, I know very little about replacing the BB... never had to deal with one on any of my bikes up until now.
How can I tell whether it needs to be replaced or just serviced? I am fairly competent, mechanically speaking... don't have a BB tool, though...
Also, are there big differences in performance and quality when dealing w/ BB's from different manufacturers/ product lines? If so, which do you think is the best bang for the buck?
Thanks again! Dick

Dick, if you don't have any BB tools, it's going to be hard for you to service/check your old BB or take it out an install a new one. Unless you want to invest in a few tools, you might want to bring it into the shop.

As generic pointed out earlier, a shimano UN-53/72/73/etc... BB would be a safe bet. There are a bunch of different models of varying quality that they made which will work. Your ultimate choice will probably be based on where you order it and what models they have in those dimensions. All of these are relatively cheap now that the square taper has gone out of favor.

Thanks again for the good advice...
In the scheme of cranksets (circa now), how do the ol' Superbe cranks rate?
Am I missing out by not upgrading to something more up to date?

I did not realize that there were the 2 square taper types. Thanks for pointing that out. What's the difference in the measurements?

If it's ISO, a current campy 111 spindle BB will substitute.
