Seatpost Collar

Description |

The Thomson Seatpost Collar gets to hug a Thomson post, which already makes it pretty lucky. More importantly, it uses Thomson’s proven seatpost bolt, washer and barrel nut hardware, allowing float on both sides of the collar slot for consistent clamping force.

Made from the same 7000-series alloy as Thomson seatposts and stems, the collar is designed to generate maximum clamping force at just 25 in-lb of fastener torque. Available in black and silver, with a 12.7mm internal collar height.
