some torque wrenches of this type will not torque past the torque value the user sets it to and will continue to click/slip as the user continues to turn the wrench.
Others will click only once at the value the wrench is set to but then will continue to tighten as if it was not a torque wrench.
It is important to get a feel for how your torque wrench functions prior to using it on critical parts that may be destroyed at relatively low torque values.
Try playing with it on the lug nuts of your car or make something else that is beefier than you will find on a bike.
