A reliable torque spanner is an indispensable tool for repair and assembly work on bicycles and should not be missing in any workshop - regardless of whether you ride a road bike, MTB or trekking bike. Compliance with the torque specified by the manufacturer (in Newton metres → Nm) is of crucial importance for safety, and not just for carbon add-on parts. The correct tightening torque ensures that the material is not overloaded and that the connection is tightened firmly enough, but not too tightly - because, as the saying goes: after tight comes loose!
