The Wolf Tooth Goatlink 11 Speed is compatible with SLX M700, XT M8000 and XTR M9000 series 11-speed shimano rear derailleurs. TheWolf Tooth Goatlink 11 Speedmounts only to standard derailleur hangers. Double chainrings (2x) is supported and requires a long cage (sgs) rear derailleur with no more than a 12t difference in front chainrings (with an 11-46t cassette). Triple chainrings are not supported. Direct mount native frames and sram derailleurs are not supported. Due to variations in derailleur hanger geometry, chainstay length, chainring size, b-screw adjustment, and suspension configuration, individual results will vary slightly.
