Wolf Tooth Components GoatLink, 11 sp Shimano Shadow
The GoatLink 11 hanger extension offsets the position of your 11-speed Shimano mountain bike rear derailleur allowing you to be able to run a wider range cassette while improving performance.
-
Same ergonomics and reliability of Shimano shifters and derailleurs
-
Gear range, simplicity and quietness of SRAM 1x11 drivetrain
-
High-performance and lightweight
This project began with the desire to run 11-speed Shimano derailleurs and shifters with SRAM 10-42t XD cassettes. Granted the combination can work without modification - but performance wasn't quite what we'd expect from Shimano and SRAM's finest.
When used with a 10-42t cassette, the GoatLink 11 re-positions SLX M7000, XT M8000 and XTR M9000 rear derailleurs such that free chain length between the cassette and the top derailleur pulley is within 1% of what Shimano intended while cassette tooth engagement in the smallest cog is improved by 27%.
Knowing that certain situations call for a range beyond that provided 10-42t or 11-42t cassettes, we tweaked the GoatLink 11 to also significantly improve Shimano 11spd rear derailleur performance with extended-range like the Wolf Tooth GCX 44t modified 10-44t XX1 or X01 cassette.

- The GoatLink 11 is compatible with SLX M7000, XT M8000 and XTR M9000 series 11-speed Shimano rear derailleurs.
- Not compatible with Shimano RD-RX812 or RD-RX817 due to the 31T capacity limitation.
- The GoatLink 11 mounts 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.

10-45t • Improved by 28%
11-45t • Improved by 36%
11-46t • Improved by 32%
9-44t • Improved by 26%
Chain Wrap in bottom cog:
10-42t • Improved by 27%10-44t • Reduced by 9%
10-45t • Reduced by 7%
11-45t • Reduced by 8%
11-46t • Improved by 12%
9-44t • Reduced by 8%
*Due to variations in derailleur hanger geometry, chainstay length, chainring size, B-screw adjustment, and suspension configuration, individual results will vary slightly.
