Modern bikes are made of modern materials and a result of squeezing out every bit of performance from those bikes and materials is the necessity of a torque wrench. It’s easy to over-do it and crack a frame or handlebar and very few of us have hands calibrated properly.
This torque wrench has a range of 2-24Nm. It’s good for 5,000 cycles or 12 months of regular use before recalibration is recommended. It’s recommended NOT to use this to loosen bolts or tighten left-hand threads.
