Perfect stem for drop bar to flat bar conversion

I got this stem in the process of doing a drop-bar to flat handlebar conversion of my road bike and it looka great, fitted perfectly so I recommend this. Just remember to use a torque wrench so you don't exceed 5 nm and risk damaging it.

Decent stem but no installation instructions for torque settings

Doesn't come with any indication of required torque setting so just applied some common sense. Not being used for jumping/downhill so shouldn't be an issue.
