The perfection of the seatpost clamp.

The Thomson Seatpost Collar has several features that make it distinct.
The collar utilizes the Thomson Seatpost bolt, washer and barrel nut system that has proven to be strong over the years. This fastener combination allows float on both sides of the collar slot ensuring consistent clamping force. The bolt hole angle, height of the collar and offset slot all help create a collar that generates maximum clamping force at only 25 inch pounds of fastener torque.

Great looks, great clamping and long life.
