Performed as needed. Fits a 30.9 into a 31.6 perfectly
Performed as needed. Was able to fit a fox transfer 30.9 dropper into a 31.6 seat post perfectly. This will allow me to swap droppers and seat posts between different bikes. Have around 200 trail miles on it so far and it hasn't moved at all.

If you own a Aventon Sinch Ebike......this is exactly what you need! I paired this with a seat suspension "REDSHIFT ShockStop" setup! Perfect Couple! Now get off your A** and Ride!

Easy to install
The item was just as described and was easy to install. It was exactly what was needed and more cost effective than buying a whole seat post.

Not quite tight enough!
The shim isn't quite as tight of a tolerance as it should have been.
