What is too tight? I just bought a new set of Deda 215 shallow handlebars and tightened down my stem connection with 4 bolts, but how do I know when tight is tight? or too tight? Is there a chance aluminum bars can snap if the bolts of the stem or shifters are clamped down to tight? I have read that carbon bars can snap if the connections are too tight. I really didn't think much about it, I always tighten them until they are very snug and will not move. Maybe I should consider a tourque wrench? Any thoughts or experinces?
