Riddle me this.... a Shimano BB question
If I recall correctly, there was a thread in the past where someone vented about Shimano compability (or lack thereof), particularly when it came to rear cassettes.
Well, recently I had to replace the BB in a bike frame. No problem I thought, I'll use an old BB of the correct size I have lying around, it's pretty good quality -only problem is that the removable cup was broken when I removed it a couple of years ago. I'll see if I can use the current removable cup from the Shimano BB in there.
So guess what? On one Shimano BB the removable cup is on the left, on the other (also Shimano brand) BB the removable cup is on the right.... WTF? I can't interchange the cups as obviously the threads aren't correct. But why do that? There is absolutely no sense to that at all to me.
Anyone any theories on this?
