We also made tests on each of our bicycle torque wrenches to make sure pre-calibrated to an accuracy of ±3% (Normal torque wrenches only at ±4% ). Easy to Use: The bicycle torque wrench is equipped with a quick adjustment mechanism making you change the torque value smoothly. And a "Click" sound can clearly tell pre-set torque value reached. There are clear Nm read-out scales in the handle, easy to read.
