I would not care that much, for the record like 8 or 7 Newtons that is what a stem clamp needs is a lot of torque, a lot more than somebody could imagine, the issue is that you have warranty and people is pretty anal sometimes with torque tolerances. I believe them when they say that they know when something is tight or not. The other issue is that the op clearly doesnt do his mechanic or the bike wouldnt be in a store to start with. So pretty much if he tight a bolt with no torque wrench probably he will leave the bolts lose or too tight, probably he has no idea how it feels to over tight something or how it feels that is not tight enough until the parts slide up or down.

If you dont want to worry about who is fixing your bike, and this is a msg to all the guys that worry about torque and are anal about tolerances and have no idea even how a torque wrench works, then do the stuff youself. Is the only way to ensure if something is done right or not.

The issue is that people just blame the store because they did something wrong, well fix a bike is not rocket science, is not even that complicated like learning diesel engines or even an advances math class. This is a subject that has come several times in the forums and is always the same thing. A poster complains about the store, well you have good and bad shop mechanics but the solution to the problems and worries is always the same, do the stuff yourself. You screw up, you'r bike wont work. They screw up you come to the forums ranting and blah blah blah... Do the stuff yourself,is the only way to get the stuff done right how you like it. The other thing, stores dont like PITA clients, and some clients are a real PITA specially the anal and ones with problems in the head like the ones with traces of paranoia.

Good luck man
