Do you need a torque wrench ? Why correct torque matters ?

Torque wrenches are rare and expensive, and most mechanics don’t know how to use them. Worse, they need to be calibrated, again, never seen anyone calibrating their torque wrench. So why it should be used anyway? There are two reasons to use a torque wrench, but with carbon bikes or carbon fiber bike parts, it is actually 3! Metals are elastic, though it may seem absurd. Yes. That’s why some people CAN complain about rigidity (otherwise it would be totally absurd, like aquaplaning resistance in road bike tires!). When you tighten a bolt too much, it elongates. This can cause two things, provided that screw holes are made from Adamantium, an imaginary metal that has infinite strongness, hardness, durability, you name it. Or Valyrian steel. Same. When elongated (or stretched) beyond certain limit, a bolt will snap, causing you too… Continue Reading Do you need a torque wrench ? Why correct torque matters ?
