Great for 10 or 11 speed deraileur
"If you are going above the capacity of your derailleur than you may require something like this. I have a grx 11 speed 2x deraileur (rd-rx810) and I wanted to use 11-46 cassette but exceeds 42T capacity so using this goatlink allowed me to use the cassette. The product is high quality. Great way to get the extra range from your setup."
