Just bought a torque wrench and some components are stamped with the torque value, some aren’t. Where can i find torque values for components? Chiefly crank bolts, rotor bolts, stem bolts, and my rear wheel (hope bolt up)

the manufacturers?

You should be able to find tables on the net for generic values but it depends on the material of the bolt and the material that is being threaded into as well as the thread form ( most bike stuff is simple metric but some is metric fine IIRC)

You then have to decide if you are going to assemble with dry or lightly oiled threads, coppa slip will again alter the values as will threadlock and at very low values (bottom 10% of range???} your torque wrench might not be accurate

In other words don’t just rely on the torque wrench – trust the feel as well

Some here

you know that wee leaflet that comes with the parts? it could be described as a manual!

RTFM !!
