Good quality handlebar stem

### ⭐⭐⭐⭐⭐ Good build quality and sturdy.
*by E***Y on 21 May 2025*

Wanted a shorter stem for a new gravel bike. Absolutely excellent. Shortens my reach and made for comfortable riding. Excellent build quality.

### ⭐⭐⭐⭐ Good quality and works fine 👍
*by M***X on 14 June 2024*

Decent casting and fitted fine. One thread was slightly iffy and stiff but running the bolt through a few times sorted that.
