    Handlebars and over tightening stem and shifters?

    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?

    Your stem should have come with some torque specs. And yes, a torque wrench is always recommended.

    Mine are marked on my stem as well as in a set of attached instructions. If yours didn't come with anything then you probably should contact the manufacturer.

    Aren't torque wrenches expensive?

    And if you know what you are doing, you don't need one. The clueless bugger stuff even with torque wrenches.

    I torque things down by 'feel' and use some common sense except when it comes down to crankbolts. I use a torque wrench when tightening crankbolts.
