I'm not sure where you are located but here in USA I just went to Harbor Freight (cheap hardware store chain) and bought a ~$20 torque wrench that has been working just great for over a year now. I have to do the conversion from in-lb to nm every time but it's no big deal. No need to buy an expensive one, even a beam torque wrench will do the job for a bike purposes.
Be careful of some of that stuff from Harbor Freight. I have bought stuff there in the past & I do get some cheap stuff there (tarps/bins/clips etc), but you are correct even a beam torque as shipped with Canyon bikes will work.
I know for a fact their mitre saws etc are not set up correctly & the last tile saw I bought was all over the map & did not last long.
For some of my tools I use Milwaukee for my home projects for the bike stuff I usually go with ParkTool or Pro Bike tool as posted above, well mainly because I can't afford to buy another trek bike
