## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value, good design, snug fit! Nothing bad to say
*by K***N on July 8, 2020*

Like:-Easily attaches to saddle and provides a very secure fit-easily inserts into frame and is very sturdy even on my 1980 garbage bike**ALWAYS BUY Anti seize lube**Dislike:- at the moment none! If it snaps mid ride I’ll let you know!

### ⭐⭐⭐⭐⭐ A bit heavy but very sturdy. Good value part.
*by A***R on July 7, 2020*

So it's a little heavy but it's as sturdy as they come. For the price it can't be beat. My 10 year olds new bike came with a post that would not extend as far as he needed to get full extension on the down pedal. This fits perfectly and leaves him a few inches of extension left to use as he grows.

### ⭐⭐⭐⭐⭐ Great product at A great price
*by J***A on June 19, 2024*

HelloVery affordable, and seems well built
