I'm trying to remove the stock cranks off of the bottom bracket of my monocog. I bought the Park ccp2 for square taper cranks. I unscrewed the 8mm allen bolt. screwed in the tool and then tightened down the wrench to do the pulling. How effin hard do I have to tighten it to get the crank to come off. I'm tightening it to to point where a giant 22mm end wrench and the tool can't move it. I have to be doing something wrong.. Help!
