    Awesome stem, great design quality, look and strength
  

*by M***T on Reviewed in the United States on July 18, 2024*

I love it. My only gripe is that its hard to tell in the pictures that the blue color does not match the other available funn parts in blue 💙💙

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good upgrade
  

*by F***E on Reviewed in the United States on May 13, 2024*

nice product, really a good upgrade for enduro mtb

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Just as good as the expensive brands without the expensive part
  

*by C***R on Reviewed in the United States on January 17, 2022*

I was looking for a 35mm stem and settled on this one after reading several independent reviews of it. This stem is made of forged aluminum, giving it strength and keeping it lightweight. What sealed the deal for me was it's price (compared to other big name brands that cost 2x, 3x, or even 4x more). Getting the Funn stem was a no brainer. I've been out riding with it for about 50 miles on trails and it has performed flawlessly. MTB parts are pricey and can add up fast. Save some of your hard earned money and get this high quality stem for your ride!
