Review: Shifts great! - Works just as well as the XO1 that it replaced. I guess it’s a few grams heavier but obviously not something that anyone would feel while riding. I’m happy I saved the money over the XO1 as functionally just as good. These things are great once you dial them in. Best shifting that I’ve ever had in a mountain bike.

### ⭐⭐⭐⭐⭐ Fantastic upgrade from SX
*by J***Y on September 20, 2022*

Two years ago I bought a Diamondback Sync'r which came equipped with 12-speed SX Eagle. It never shifted particularly well and had a severe chain slap problem. At the urging of my bike mechanic brother in law, I bought this derailleur and also a GX shifter and installed them on my bike. Night and day difference. Shifting is crisp and smooth even under load, and the chain slap is totally gone. Can't recommend this enough as an upgrade from SX. For a reasonable price it'll make your bike run better than ever. (Note that I kept the original SX/NX cassette and it works perfectly well with the GX derailleur.)
