Seat Post Reducer Shim Bushing
This shim set is used on 25.4mm seat posts to adapt them to frames with a seat mast inner diameter ranging from 26.4mm up to 28.0mm.
Notice the "scoring" on the shims. On the tall shim, the two lines are for 27.0mm (bottom) and 27.2mm (top). You would use a tubing cutter or other device to cut the top of the shim for those applications if you didn't want the rest of the shim sticking up above the seat clamp/seat mast.
The shorter shim is the thinner of the two so would be for the smaller seat masts like 26.4mm.
This is a universal shim set and as described above may require cutting to make it work with your application. As with all of our products, we always recommend installation by a professional bicycle mechanic as we do not provide technical assistance.
