I will give it 3 stars for now. Unlike SRAM 12-speed chains, this one does not work with my E-thirteen TRS Race Cassette due to the extreme tight tolerances of my bike and drive train setup. It skips off the last 3 cogs (goes inwards) when I back pedal. I do NOT have this issue with SRAM 12-speed chains. I do have a bike with XX1 Eagle, so I try it on that bike when the chain wers out . This chain though does look nice and well made! I will come back and review again once I put it through the ringer.
