    And the point of this thread is what? Learn proper torque values?

    Torque ratings are written directly on a lot of components now, especially carbon, but maybe it was hidden underneath the clamp. Otherwise, you might want to try one of these made by Ritchey, its a torque key with just one torque setting that is correct for the majority of stems and bars, the only problem is that it only has a 4mm allen key (which means that it works well with Ritchey's high-end equipment).

    Even if you could find the info elsewhere, getting it directly from the manufacturer is the best source. While you're at it, you can ask whether they recommend any particular type of stem, any stem's to avoid, etc.

    That's the problem sometimes with CF components....they're like nitroglycerine.....be rough with them and they can "explode" on you......
    We never needed to worry too much about exacting torque values before CF came into the scene. I felt kinda strange telling my teenage nephew who is really getting into biking and had just bought his first carbon framed bike, that he has to remember to be careful when tightening fittings and components on his frame. I know I had to warn him about it, but me not owning a new CF bike, is just as clueless about how you really deal with it.
