USE Thermoplastic Shim

The USE shim system allows you to fit a post into virtually any frame size. Our shims are made to 100mm length and are longer than other shims on the market. This gives your seatpost much better support inside the frame. All shims are designed with a "top lip" to stop shim sliding into the frame.


  • The Thermoplastic shims area a larger size, and are machined to very high tolerances from "filled" engineering thermoplastic UPVC. This keeps the weight down, as the shims get thicker.
