Dont mix and match
Will not work through all 12 sprockets of Bucklos cassette. I am using it with a shimano 12 speed shifter in a 1x12 setup. The problem is with the smallest COG. Dont think it is a quality problem but try not to mix and match

replacing a bent Shimano Deore 12 speed
Replacement for an original . Just reqquired some adjusting then fine tuning to get it to shift smoothly. You Tube has many videos covering this if you are unsure how to do this. Price was better than expected. Overall very happy with my purchase.

Works great
Replaced it on the Grand Canyon 5. It is identical to what I had on the bike. P.S. Packaging could be better.

Fine product but not sealed
The box was open and the plastic bag containing the product was not sealed (Torn). Difficult to say if product was indeed new or refurbished
