Works great!
I was skeptical that it would fit ok given the very small diameter difference, but it works great! No seatpost slipping at all and I now have a dropper post I otherwise wouldn't have been able to use.

Lived up to its name.
Lived up to its name, solved the problem, and you could hardly see it. I could have exchanged the post, but the cables went through the frame, and I would have to wait an other couple days till the mechanic could get to it. I just had the bike built and it was the only thing keeping me from a planned ride with friends. Stoked!

Solid solution
Does its purpose without a problem.

Don't be afraid to use it on carbon frames. Use carbon paste for the outside and grease for the inside

What a great item. Jenson always quick shipping to Utah and reasonably priced. Have a Trek Hardtail wouldn't hold seat post even after swapping out post and clamp. Bike was not useable if you road any rough terrain seat slowly worked down killing your knees. Bought the shim and it was a perfect fix on my 31.8 tube.
