Bicycle Alloy Seat Post Shim – 31.8mm To 28.6mm, Silver

Got a seat post that's too small for your frame?

This alloy shim takes a 31.8mm post down to fit a 28.6mm seat tube.

Silver, simple, does the job.

Unbranded, new.

Lets you use the post you want without wobble.

Good for bike builds or swaps.
