Carbon assembly paste …

    … is magic stuff. Installing Campagnolo levers on carbon bars, I torqued the clamp bolt up to the recommended 10 Nm, which felt pretty high for carbon bars, but the levers still moved sideways if I pushed on them. I had the end of a sachet of FSA “installation compound” which came with a carbon seatpost (red stuff, identical to Ritchey “Liquid Torque”), and smeared a little on the bars where the clamps sit. The difference is really amazing. With the bolt finger tight the clamp immediately felt sticky, making it harder to move by small amounts without jumping too far. With the bolts at 8 Nm the levers are rock solid.

    Ask manufacturer if its dry
    Ask manufacturer if its dry or wet torque settings?

    The Campagnolo 11-speed Egro
    The Campagnolo 11-speed Egro Lever instructions say 10 Nm torque. (I didn’t check if there was a recommended max. torque for the FSA carbon bars. If there is, it will likely be higher on the less crushable, smaller diameter part of the bars where the levers clamp.)

    Torque values do seem to vary a lot, depending upon component and manufacturer. eg: I have an FSA stem which recommends 6 – 8 Nm for its bolts, but a Salsa stem which says 4 Nm.

    I bought a torque wrench because I was taking some bars on and off a stem a lot to pack a bike for travel, and I wanted to make sure that I wasn’t to either damage the threads or not have the clamp tight enough.

    2nd that but can you confirm
    2nd that but can you confirm the recommended/max torque as I was under the impression it was 5Nm?

    Never tried it for levers
    Never tried it for levers before, what a great idea.
