Utilizes the Thomson Seatpost bolt, washer, and barrel nut combination that 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
The Thomson Seatpost Collar is made from the same 7000 series alloy as their seatposts and stems, giving you the high performance and long life you expect from a Thomson
