The Thomson Seatpost Collar is made from 7000 series aluminum and carries Thomson’s well-known precision machining quality and long-term durability. It is a clean, practical and well-made upgrade for any refined bike build.
Although a seatpost collar is a small component, it plays an important role in seatpost security, riding stability and noise control. The Thomson Seatpost Collar provides consistent clamping force to hold the seatpost securely, helping reduce the chance of seatpost slipping, loosening or creaking caused by poor contact.
Its simple and clean design pairs naturally with Thomson seatposts, stems and other silver or black components. Whether used on a single speed bike, mountain bike, road bike or custom build, it is a small but effective detail upgrade.
Available in black, silver and raw finish, with 29.8mm, 31.8mm and 34.9mm sizes to fit different frame requirements. Weight ranges from approximately 26g to 30g depending on size, offering a good balance of low weight and reliable clamping performance.
If you are looking for a precisely machined, durable and understated seatpost collar with strong clamping performance, the Thomson Seatpost Collar is a trusted USA-made choice.
