Thomson seatpost collar
$ 31.95
The Thomson collar utilizes the seatpost bolt/washer/barrel nut combo 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 20-25 inch-lbs of torque.
