OP, I doubt you have any ultra-light carbon stuff like handlebars, but you have to take the torque recommendations with a grain of salt. In other words be even more careful than the torque recommendation suggests. I had a Kestrel handlebar that said use the stem maker's recommendation for torque. That was 6 Nm. The bar cracked at around 4. Guess what? The replacement of the same model is plenty tight at 2. So really use the recommendations as an absolute upper limit. You will rarely need to go that high.
