This was just what I needed. Bought to fit a 26.2 seat tube with a 29.4 accessory so bought the 27.2-30.4 shim and squashed it a bit. Had to cut a bit of spare metal off with a hacksaw, but the item does exactly what I needed with a bit of modification. Apparently 26.2 is not a standard diameter. I am grateful for SJS staff for suggesting the fix!

Could you recommend a seatpost or seatpost shim that would be a suitable fit please(shim preferably for a 27.2 seatpost as that is a more common size).Thank you for your assistance.
Kind regards

The product you need is - SJS Cycles part number : 2975S296
Just select the 29.6mm size.

Would The 28.6 O.D. Fit 1 1/8 Ahead Stem?
08 Apr 2017
Need a spare shim for my 1 1/8" Ahead stem attaching to 27.2 tandem seatpost

You are correct, the 28.6mm size will be suitable for use with a 1 1/8" ahead stem.

What Length Are These?

I would be buying the 27.2 29.8

These shims are 80mm long.
