tool torque~a little click


It's a sickening feeling.Just as you tighten that crank bolt the last little bit, you suddenly  feel it'give'.And there goes the thread, a lot of hard work and expense.
               
I've recently become a big fan of torque wrenches. I suspect it's because they appeal to my sense of orderliness. Just dial in the required torque and apply steady rotational pressure until you feel  a little click. Perfect for achieving equal torque for 5 chain ring bolts, the aforementioned crank bolt or perhaps the bolt of a shiny Nitto stem..

Note:most bicycle part manufacturers will advise the correct torque for their products. Alternatively, try Park Tools web site or Leonard Zinn's 'Zinn and the art of road mountain bike maintenance'for a comprehensive table.

(and that sinister looking beak shaped tool at the bottom of the frame?It's my grandfather's antique nail puller. Must be over a hundred years old and you can rip out almost any rusty old nail with that thing.And if it won't budge? It just rips the head right off.)
