    Saw a company on the net somewhere that was selling CF posts for Bromptons. Had the necked down top for the Pentaclip,just like the stocker.

    I'm not worried about CF just suddenly failing;I know two people that had steel forks suddenly go on them. But in this case,there's too much post sticking out,too little clamping area,and the post is regularly being 'reclamped'. On my road bikes,I set the seatpost height once,tighten the clamp with a torque wrench,then leave it alone.

    Thanks for the warning guys... I think it's pretty clear my carbon seatpost just isn't meant to be on the Brompton. Not to mention I'd agree the weight savings is negligible to be absolutely not worth the risk.

    Appreciate it.

    Thanks. Going to collect my wheel tmr with the A2 installed. Hopefully it doesn't need tweaking.

    On the Brompton its unusable stock, may be ok on a 20" wheel though depending on if you get the 20 or 26" version.

    Its pretty easy to change if you are semi mechanical minded, though there was some discussion about the warranty if you do.

    Details of how adjust the change point scroll down to the bottom of the page.

    RE cf seat post, that would be an upper 2 stage telescopic?

    there are bushings to Modify the existing seatpost , after cutting it off,
    then slotting it and adding a 2nd QR on top of the standard post .
