One of the best upgrade options out there! Not only does the Thomson Seat Collar look awesome, it also works incredibly well, as would be expected from the company that brought aerospace engineering and cycle componentry together to create superior CNC machined bike parts. The seat collar is made from beautifully machined high strength 7000 series aluminium (the same type as is used for Thomson’s stems and seatposts) and is designed to clamp the seatpost consistently and effectively with just a very low torque (2.8Nm), making it a great option for delicate carbon posts/frames. This seat collar is a premium option which will not break the bank – or your carbon post! A win-win option.
