Product Description The best of both worlds: the GoatLink 11 Rear Derailleur Adapter by Wolf Tooth Components It all began with a desire to ride Shimano 11-speed rear derailleurs and shifters with SRAM 10-42 XD cassettes without sacrificing performance. It took Wolf Tooth eight months to develop the Lindarets x Wolf Tooth GoatLink 11, which helps combine the reliability of Shimano rear derailleurs and shifters with the simplicity and smoothness of an SRAM 1x11-speed drivetrain. When using a 10-42 cassette, GoatLink 11 optimally positions the Shimano XT M8000 and XTR M9000 rear derailleur. You can also use the GoatLink for extended cassettes such as 10-44 Z XX1.
