I'll give those ideas a try. I'm using CPP-2 for square-tapered BB, how can I be sure that i'm using the right tool? Is there a way for me to look at the cranks (with the 8mm bolt off) and know if I need a square-tapered tool, or the Octalink/ISIS type tool? When I look through the hole in the crank, I can see the square cutout with a circle inside, so i'm assuming i'm using the right tool, how can I tell for sure?
