Thomson Seatpost Collar

The floating bolt, washer, and barrel nut system allows the clamp to apply pressure evenly across the entire slot. This prevents the uneven clamping force that can often damage carbon fiber seatposts or frames.

This specific model has a clamp diameter of 34.9 mm. You should measure your seat tube's outer diameter or check your current seatpost clamp's specifications to ensure a proper fit before purchasing.

The maximum recommended torque for this seatpost collar is 2.8 Nm. We recommend using a calibrated torque wrench to ensure you do not exceed this limit and compromise the hardware or your frame.

Yes, the offset slot design and even pressure distribution make it a safe choice for carbon components. However, always verify your frame manufacturer's specific torque requirements, as they may be lower than the clamp's maximum.

The stack height is 12.7 mm. This low-profile measurement is important if you have limited space on your seat tube or if you are trying to avoid interference with other frame accessories.
