Seatpost ShimsOur seatpost shims reducers allow you to have a smaller size diameter seat post. These shims will insert directly into your bicycle frame and will allow you to use a seatpost with a smaller diameter. Our Seatpost Shims are what you need when your seat post is a little too small in diameter to fit tightly into your frame. Each shim is lightweight, durable, and have a lip on the top so it won't slide down inside the frame during installation. Perfect
