### ⭐ 







  
  
    Wrong size?
  

*by S***S on Reviewed in the United States on July 30, 2019*

I first bought the 70 mm length, I used it for a few rides and felt it was a little short. I tried the 90 mm, same thing but maybe a little too long, so returned those and ordered the 80 mm length. Perfect length, but I tightened it completely and the handlebar was still loose. I thought I just got a defective stem, returned it and received another 80 mm. Same thing! Tightened all the way, and the handlebar can still be moved with a little force? So I'm returning this one as well. The only one I had this problem with was the 80 mm length. Shame, because I really like the stem.

### ⭐⭐⭐⭐ 







  
  
    Had to return the first one.
  

*by D***R on Reviewed in the United States on March 11, 2021*

One of the holes wasn't drilled and tapped deep enough.

### ⭐⭐⭐⭐⭐ 







  
  
    Make sure you know your stem and handle bar size.
  

*by B***Z on Reviewed in the United States on July 5, 2019*

The item is just what expected. Changed my aluminum stem. Weight reduction and the proper fit for my Specialized Stump Jumper.
