I find conflicting advice on Cartridge Bottom Bracket installation, especially those with plastic adjustable rings. My experience with these is limited, so I've searched the forums and there have been numerous problems with the plastic rings cracking when torqued down to 360 in-lbs as recommended by the Parktool site, and also the Barnett's manual. One poster said that several bike shops he went to for a replacement ring said to always just snug up that adjustable ring against the body, don't torque it down, because it's not a press- or taper-fit.
My question is, if you have already just snugged the body into the shell, then if you just snug the adjustable ring against that, where's the torque?? Doesn't at least one of these parts need to be torqued down to prevent movement and creaking? I'm so confused. Would you tighten the body to a torque spec, and *then* just snug up the adjustable ring?
