## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for my e-bike
*by I***3 on June 29, 2025*

Worked great to replace the stem/neck that came with my ebike. Save me some weight and gave me a lower profile that I wanted. Quick swap out and great price.

### ⭐⭐⭐⭐⭐ Fits Right
*by B***H on March 27, 2025*

Exactly as listed, diameters and length are both correct. Well finished and strong enough for general use. Beware of others that say they're 180mm but are only 150mm. Two thumbs up.

### ⭐⭐⭐⭐⭐ Worked perfectly
*by M***E on October 18, 2024*

Raising my handlebars after putting on a shock absorbing adapter for the handlebars.
