The Cane Creek Seat Post Shim converts a 34.9mm diameter seat tube to a 30.9mm diameter, allowing for compatibility with a wider range of seat posts. Made from durable aluminium and finished in sleek black, this shim is designed to seamlessly integrate into your bike's seat post for a smooth and secure fit. Perfect for cyclists looking to upgrade or adjust their seatpost diameter, the Cane Creek Seat Post Shim is a reliable and high-quality component for your bike. Used, so (as seen in images) there’s some visible corrosion to the surface finish. As you can imagine, this is not visible once installed.
