The wrench needs to be accurate at relatively low torques - from say 2.5kN (front mech band) through 6-8kN (stem bolts) to 12kN (crank bolts). If it's aimed at higher torque range then it won't be as accurate at low torque settings as a bike torque wrench.

I mostly use a torque driver rather than a wrench.

They work at much lower ranges. I have one of these for small jobs

Then one of these for bigger jobs

I always work of Nm (Newton Meters) rather than kN, which I believe is just 1000 Nm? Thinking

Got mine from Screwfix and it is great and about half the price of a "cycle specific" one

The Sealey STW1012 (2- 28 Nm)is an accurate, fairly low cost torque wrench which is popular amongst many cyclists including me.
