### ⭐⭐⭐⭐⭐ Good chain tensioner
*by R***A on September 29, 2025*

Works for converting mtb to a single speed!

### ⭐⭐⭐⭐ Decided I wanted a smooth roller instead
*by P***N on July 13, 2025*

Can't say anything was wrong with it, but I decided I preferred a chain tensioner without teeth: that is, a smooth roller. I returned this item.

### ⭐⭐⭐⭐⭐ Worked great!
*by T***N on September 15, 2024*

This fit on my single speed ebike right to the bolt and added the needed tension! I needed to pull off the end cap of this thing to adjust the spring load angle, which took a few tries, but ended up doing well. It looks good, and feels durable enough.
