## Customer Reviews

### ⭐ 1.0 out of 5 stars







  
  
    Not strong enough. Mine bent.
  

*by T***O on Reviewed in the United Kingdom 🇬🇧 on 15 April 2023*

Was OK until I went over a few bumps. Then it bent. There's a lot of leverage on it, but it should be strong enough for the length they offer. It's quite thin. Needed a shim to bring it up to the 25mm needed for the seat tube.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Best seat post ever!
  

*by G***E on Reviewed in the United Kingdom 🇬🇧 on 31 March 2022*

Perfect seat post for the adult rider, fit's great and it's really sturdy. Fantastic quality, like all the bike parts I've bought from this company. Most of this supergoose bike build came from this seller, best quality products I've purchased on Amazon. I definitely recommend both this seller and products, I will always be buying from this company from now on.
