Any way to identify model of installed BB?(3 posts)

Any way to identify model of installed BB?Ed2
Mar 30, 2001 5:57 AM
Hi,
Just picked up a used frame with an old bottom bracket installed.
I believe it is a shimano model, older non-splined model.
Is there any identifier, name, colour that I can use to determine the model, without removing the bb itself?
It is probably an RSX model, but just wanted to know for sure.

Thanks,
Ed

....and see if you can look thru spindle. On tapered ones, you can cee through the quality ones like the un-72, and the cheaper ones are solid.

Some of the really cheap cartridge types install from the non drive side with the lock ring on the drive side, and have a parkerized or phosphate type greenish finish.
