The USE shim system allows you to fit a post into virtually any frame size. USE shims are made to 100mm length and are longer than other shims on the market. This supports the seatpost inside the frame. All shims are designed with a "top lip" to stop shim sliding into the frame. Depending on the thickness of the shim, it is made from either Rolled Aluminium, Machined Aluminium or Thermoplastic.
- USE Seat Post Shims
- Rolled Aluminum shim - the very thinnest shims are rolled from sheet metal. 25.4mm shims need to be so thin as they are etched down in acid to the correct tolerance and are too thin to anodise
- Machined Aluminum shim - machined to very high tolerances from 6082 T6 Aluminum and then black anodised to protect from corrosion
- Machined Plastic shim - larger size shims are machined to very high tolerances from "filled" engineering thermoplastic UPVC. This keeps the weight down, as the shims get thicker
- Sizes: See below
