## Customer Reviews

### ⭐⭐⭐⭐⭐ Makes the bike more comfortable to ride
*by P***N on 28 June 2024*

Seems a nicely made item. The 90mm version was about 130g heavier than the previous stem which seems ok to me. Good value for money and easy to fit.

### ⭐⭐⭐⭐⭐ Perfect fit
*by D***  on 3 July 2024*

Good quality item and good price.

### ⭐⭐⭐⭐⭐ Great upgrade for my Son's Kids Specialized.
*by D***L on 28 May 2024*

My lad has a Riprock 20. Why Specialized have the handle bars so low is weird, I think it's an aesthetic thing. This has done a great job of not only raising the handle bar but it also brings it inwards a bit. He's much more comfortable now. It's decent quality as well.
