Lockring for ISIS Bottom Bracket?
I'm swapping out a Truvativ ISIS triple crank for a Shimano Ultegra double on my '05 Cannondale CAAD7. I picked up a Shimano Octalink V1 BB to go with the new crank.The ISIS BB that is on the bike at the moment appears to have some kind of lockring holding it on. As far as I can tell, the Octalink bottom bracket that I will be replacing it with does not have a lockring and is held in place by the retaining cups on each side. My question is: do I need a lockring spanner to take this thing off, or will a large pair of channel locks suffice, since i won't be reusing the lockring once it is removed?
