Bike stem top cap torque.

There are basically three types of torque wrenches the beam type the click type and the dial type. Torque the pinch bolts. A torque wrench is a good idea at this point. 100 120 lb in 11 3 13 6 nm handlebar clamp.

The specs on alot of my parts like the carbon stem and seatpost clamp indicate a max torque of 5nm which was way more than i would have done if i was just hand tightening.

You can absolutely over tighten the bolts it is after all most likely lightweight aluminum you re working with. With carbon fiber handlebar. 150 180 lb in 17 20 3 nm handlebar clamp. 100 120 lb in 11 3 13 6 nm handlebar clamp.

Do not overtighten it. Never had anything close to an issue with the lower than max torque. This is precisely why almost all stems have torque values printed on the actual part. A typical torque spec is 4 6 nm.

If you feel play loosen the pinch bolts tighten the top cap another 1 8th turn re tighten the pinch bolts and check again. 100 120 lb in 11 3 13 6 nm stem angle adjustment.
