dura-ace BB - how to torque?
the dura-ace crankset comes with a special shimano tool for the bottom bracket cups. you are supposed to tighten them to a specified torque setting, but how can you attach the supplied wrench to a torque wrench?
a normal BB tool has a large nut-like section that you can put a socket over.
Tighten them the same amount that you would normal BB cups. The drive side needs to be tight or it will loosen off, then the oppisit side snugs up give it one more umph of torque. Its the arms that have specific torque.
