I just installed a Hollowtech II Ultegra crankset on my bike here. Looking at the instructions, the attorney wanted me to torque (torque-wrench with measurement, used a Park beam one) the 2 x 5mm hex-bolts, slowly and evenly, to between 120 ip and 132 ip (inch-pounds). Got up to 125ip on one side - and the alloy bolt began to show signs of stripping on it's head.
You were saying? This IS Shimano, you know.
