Torque wrenches
A quick scan on the various topics floating at rec.bicycles.tech will
always show several topics involving fastener tension (cranks loosening, chainring bolts, spoke tension). There is a range of "correct" or acceptable torque for any bolt. The idea of torque is to arrive at enough tension in the fastener. If you could simply pull on the bolt enough with your fingers, and run the nut down, it would work as well. There are more accurate ways than a torque wrench for determining thread tension. However, a torque wrench is simply the most practical. Again, a torque wrench in only a measuring tool. Using a torque wrench cannot replace thinking and paying attention, but it does give mechanics of all types a common language. Working with a torque wrench can help a mechanic develop a sense of what 360 inch pounds (many crank bots), or 4 inch pounds (Hollowtech II crank caps) "feels" like. Experience with measured torque will allow useful conversations between mechanics themselves, and between engineers/manufacturers and mechanics. Without knowledge or experience in torque, it seems we will continue to exchange poetic verse, such as "tighten the crap out of it", "snug it up", "thumb tight", "loosey goosey", "pretty tight", or, "%@!$! Tight". |

It looks much easier to calibrate than the click-click torque wrench I've got. -- --- "I never had to pretend I felt the lyrics. I could always relate to the words." --Teddy Pendergrass |
