I don't know from quarq, but do you really think it has to be that precise? I mean who uses a torque wrench on chain ring bolts? I would just hand tighten and go. What is going to happen? As far as coming loose is concerned, I have never seen a chain ring bolt that wasn't the devil to loosen. I wouldn't worry about it. Until carbon fiber parts were introduced, you never heard of anyone using a torque wrench on a bike. Now, of course, it is rather important, but not for every part assembly. Besides, my LBS tells me that the listed torques are more related to material protection, not safety. Safe tightness occurs at much lower torques. Oh, and by the way, what makes you think that that the Ritchie torque key is more precise or even accurate than your TW-2? If you set the TW-2 to 10 nm, I don't see how you could go wrong. Enough torque for safety, not too much to protect your parts.
