I was putting the rear sproket back on my bike today. The nuts are supposed to be 72 ft lbs. I brought them all down gradual using the proper criss cross pattern just like in the manual. I got to 65 ft lbs ok but when I started torquing at 72 ft lbs 2 of the nuts seemed to turn to far and no click on the wrench, the other 4 clicked the wrench(snapon) I didn't want to keep turning them for fear of really f--king them up. I rechecked those two at 65 and they clicked the wrench. Anybody had this problem before and any ideas? These are 17 mm nuts. Should I just leave them all at 65 ft lbs? Tee Tee, Guys help!
