    Hi all.
    I bought a bike over the weekend & there are a few carbon parts on her. I need to make a few adjustments before I take it for a spin. My question is, using a torque wrench, what's a safe level to tighten carbon parts to without cracking the carbon?

    Most parts will have it printed on the parts.

    Try the manufacturer's web site first.
    Here is a sample from the Planet X site.
    Torque Settings?

    These are our recommended torque settings for our carbon frames.

    SL Pro Carbon Road Seat Clamp: 5.8Nm to 8Nm
    SL Pro Carbon Road Front Mech Clamp: 3.5Nm
    SL Pro Carbon Road Fork Steerer to Stem Clamp: 5Nm to 8Nm

    Stealth Seat Clamp 6Nm to 9Nm
    Stealth Carbon Fork Steerer to Stem Clamp: 5Nm to 8Nm
    Stealth Carbon Handlebar Clamp: 5Nm to 8Nm
    Stealth Carbon Arm Rest/Extension Clamps: 3.5Nm

    For the metal on metal bits try here.

    Thanks for the advice lads. I have checked the parts but there's no clear indications.
    At a glance it seems between 5-8Nm is the general rule but I'll check manufacturers sites for a definitive answer
