    QR Seatpost Clamp on Carbon Frame

    I want to use a QR clamp in place of the standard on my new Stumpjumper HT 29er Carbon - but the manual says:
    "Specialized Stumpjumper carbon hardtail frames use a seatpost collar specifically designed for these frames. Use of a different collar can cause damage to the frame or seatpost, resulting in failure"
    This is my first carbon frame...do I need to take this seriously? Browsing the web I don't seem to see clamps marketed specifically for carbon, is there anything different?
    Anyone have a Stumpjumper HT carbon with a QR clamp?

    Don't know about Speci; but I have a QR seat post clamp on my Carbon Nomad no problem with it.

    Thanks Dwill; was the QR on your Nomad specially chosen for Carbon? Did your manual have any warnings?

    I would assume that they publish a torque to tighten the clamp. Excessive torque would be potentially a problem. It would be difficult to control the torque with a QR collar.
    The trouble with having an open mind is that people will insist on trying to put things in it.

    Yes, a torque is published but sad to say I don 't have a torque wrench that goes that low so I just tighten it up to what fels right... not too tight. I suppose, another solution would be a dropper seat post - oh no, more spending.
