Seatpost Lock: Clamp

  • Our seatpost clamps are precisely machined from a billet of a carefully selected aerospace grade aluminium before being beautifully anodised in one of a wide range of colours.

    The clamp is secured using a 6AL4V titanium fastener encoded with your unique infiniti3d security™ key and fully recessed to thwart attacks from gripping tools.

  • A barrel nut provides silky smooth operation and optimal clamping efficiency.

    Our security seatpost collars are currently available in four sizes: 28.6, 30.0, 31.8 and 34.9.

    Please note that the above dimensions refer to the diameter of the seat tube of the frame, not the diameter of your seatpost.

  • Why are our seatpost clamps different?

    Unlike the majority of 'high end' products on the market, our seatpost clamps are machined gently, preserving the integrity of the microstructure of the material which results in a far superior product. It always amazes people to know that the product they see has not been through any polishing media or finishing process prior to anodising.

  • Why? We don't need to try to eradicate the marks from aggressive machining!

    If you are unsure which size to order or do not find the size you are looking for then please do not hesitate to contact us.
