Thomson Seatclamp

This clamp is designed for frames that require a 29.8 mm seatpost clamp diameter. You should verify your frame's specific seat tube outer diameter, which is often printed on the existing clamp or listed in your bike's technical specifications, as this measurement must be precise for a secure fit.

Yes, the Thomson seatclamp is generally safe for carbon components, provided you adhere to the manufacturer's torque specifications. Because it is a bolt-on clamp, it provides consistent, even pressure, which is ideal for protecting delicate carbon surfaces.

This model uses a bolt-on mechanism. This design is preferred by many riders for its clean, understated aesthetic and because it provides a more secure, tamper-resistant hold than quick-release alternatives.

Thomson's anodized finish is highly durable and resistant to the typical wear and tear of cycling. While any metal component can scratch if impacted by tools or debris, the anodization process bonds the color to the metal, ensuring it maintains its appearance significantly longer than painted finishes.

You will need a standard hex key (Allen wrench) to tighten the bolt. It is recommended to use a torque wrench during installation to ensure you reach the correct tension without over-tightening, especially if you are using a carbon frame or seatpost.
