27.2 Seatpost Shim

Here is the Seatpost Shim for a 27.2 post. Lathed and milled out of a 304 SS tube.

The slots are here for a couple of reasons, Reduced weight and is a good place to feed in the silver, for a secure bond to the ID of the seat tube.

The top image is of the shim only, and the second pic is of the shim inside the seat tube.
