Didn't you write Shimano 600 earlier?

Yes, this is what is printed on the cranks and the gear shift levers. I thought this was a.k.a. "Shimano Dura-Ace."

The classic New Dura Ace BB interchanges with Campagnolo
1046A which is a different taper section than the most
common[1] modern cartridge crank spindles and asymmetric as
well.

Are you saying that the typical modern cartridge crank will not fit my bike? Also that I need an asymetric cartridge and this will cost me more?

What does the Campagnolo 1046A have to do with this?

If it's a BB7400 I would rebuild it or have that done. Nice
product well worth keeping IMHO.

Is "7400" going to be stamped on the bottom bracket somewhere and evident when I take the BB apart?


[1]There are good cartridge replacements but not for $15


That's fine. But from what you wrote, now I cannot tell whether one even exists for my Vitus 979.

The 7400 should be on the left side lock ring if memory serves. Most BB's don't but the Dura Ace 7400 was an exception.
