Fouriers Bike Seatpost Reducer Shim(31.6mm-30.9mm)

I just wanted to give it 5 stars and be done with the review, but they require a description on Amazon...so I'll post my mom's secret chocolate chip cookie recipe here instead (not so secret anymore, is it, Mom!?):4 cubes butter, softened2 heaping cups dark brown sugar (packed, then heap that shiz)½ cups white sugar2 tablespoons vanilla1 ½ teaspoon salt1 ½ teaspoons baking soda3 eggs6 cups flour1 bag chocolate chips (semi-sweet or sweet)Mix BY HAND all ingredients, except flour and chips (mixing by hand makes them taste better, trust me).Then add flour and chips and stir BY HAND. Bake @ 350 for 9-11 minutes on ungreased cookie sheet. Enjoy the preciouses.Note: makes a buttload of cookies, so you might want to halve the recipe.

Perfect solution to get my 30.9 dropper post to fit in a frame for 31.6 posts. Easy install and holds just as tight as the frame metal.

Worked great until the lip broke after two years of occasional use, and ended my bike ride. Have since read I should use carbon paste to increase friction which relieves stress on the lip, I'll try that this time around.

I bought two different brands and this was the one that saved the day! The other brand didn't fit right. Also note my frame is double butted and this reducer allows the dropper post to sit more than 4" into the 31.6 frame with 30.9 post which helps my short 🍑. Thank you Fouriers for a great product!

This is a plastic cheaply made piece. I don't recommend it. You can find an aluminum one for around the same price
