Review: 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. Review: 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. ## Features - Size: Handlebar Diameter: 31.8 mm.
