Thomson Seatclamp

The 36.4mm measurement refers to the outside diameter of your frame's seat tube, not the diameter of your seatpost. You should measure the outside of your seat tube with a caliper or check your frame manufacturer's specifications to ensure a perfect match.

This is a bolt-on clamp. It requires a hex key to tighten, which provides a more secure, permanent fit and a cleaner aesthetic compared to quick-release levers.

Thomson's anodized finish is highly durable and resistant to the elements. While it can be scratched by metal tools if you aren't careful during installation, it is designed to maintain its color and luster through years of regular use.

Yes, it is compatible with carbon frames, provided the diameter matches your seat tube. When installing on carbon components, always use a torque wrench to ensure you do not exceed the manufacturer's recommended torque settings to avoid damaging the material.

Beyond the aesthetic upgrade, precision-milled aluminum offers superior clamping force and consistency. It is less likely to deform over time, ensuring your seatpost stays exactly where you set it without slipping.
