Maybe your pants after the first part fails unexpectedly or drops off due to incorrect torque values....


The reason I feel rather strongly about torque wrenches is that bike parts are engineered to razor thin margins of safety due mostly to weight concerns, and it is really easy to damage bike parts with the wrong (however well-meaning) torque value. I have been wrenching things for over 40years, and every now and then, I assemble something non-critical and try to guess the torque I'm applying, then use a torque wrench to check. I'm never close enough to be as arrogant as to say I don't need one. I do - and use one whenever the manufacturer specifies a torque value.
