ULTIMATE USE 30.9 Internal Shim

This ULTIMATE USE 30.9 Internal Shim allows you to fit a 30.9mm seat post into virtually any frame size. The shims are made to 100mm length and are longer than other shims on the market, giving your seat post much better support inside the frame.

High-Quality Construction

These machined plastic shims are machined to very high tolerances from "filled" engineering thermoplastic UPVC. This keeps the weight down, as the shims get thicker.
