Edit: I guess ISIS also comes in a version that use a traditional pin wrench lockrings:
I learn something new every day...
Missed this post. Ok, I wondered when I saw the setup if it might be old-school--I did mess with the cup and cone BB on my Raleigh, so I know the tool you are talking about. Of course I don't have that one... but your pic does look a lot like what I have.
Of course mine is kinda screwy, it has an oring on it, that does nothing, seemingly. I was able to easily pry it off. Seems odd that it doesn't bottom out. [The red bike does not use this o-ring setup.]
Edit: o-ring sits in the groove here; I pried it out for this photo. It basically fills in the groove for aesthetics I'm guessing.
