Description of Wolf Tooth GoatLink Range Extender for Rear Derailleurs - black - 11-speed

Note: Delivery includes only the GoatLink 11. Other products shown are solely for illustrative purposes and are not supplied.

Lindarets and Wolf Tooth Components have teamed up to optimize Shimano 11-speed XT and XTR derailleurs for use with SRAM XD cassettes. When used with a 10-42t cassette, the GoatLink 11 re-positions M8000 XT and M9000 XTR rear derailleurs such that free chain is within 1% of what Shimano intended while engagement is improved by 27%.

The GoatLink 11 also significantly improves Shimano 11s rear derailleur performance with extended-range 10-44t and 11-45t cassettes. It provides ideal performance from 10-42t XD cassettes and wide-range capability for bigger days.

Each GoatLink is CNC machined from 6061 aluminum, anodized, and laser etched at Wolf Tooth Components' Minneapolis facility.

Cassette - Compatibility
  • 11-40: Not Required
  • 11-42: Not Required
  • 11-45: GS/SGS Derailleur
  • 11-46: GS/SGS Derailleur
  • 10-42: GS/SGS Derailleur
  • 10-44: GS/SGS Derailleur
  • 10-45: Not Optimized
  • 9-44: Not Optimized

The GoatLink 11 is compatible with M8000 (XT) and M9000 (XTR) series 11-speed Shimano rear derailleurs. The GoatLink 11 mounts only to standard derailleur hangers.

Note: Triple chainrings are not supported. Double chainrings (2x) are supported and require a long cage (SGS) rear derailleur with no more than a 12t difference in front chainrings (with an 11-46 cassette). Direct Mount-native frames and SRAM derailleurs are not supported.

All improvements are based on nominal Shimano-specification derailleur hanger geometry. An unmodified Shimano rear derailleur adjusted for the specified cassette serves as the baseline (0%), and an unmodified rear derailleur adjusted for a 40t top cog as the target (100%).

Due to variations in derailleur hanger geometry, chainstay length, chainring size, B-screw adjustment, and suspension configuration, individual results will vary. You will NEVER need a longer B-screw when using a GoatLink!

Note: For M8000 (XT) and M9000 (XTR) series 11-speed Shimano rear derailleurs only!

Geniale Ergänzung für 1-fach Antriebe
Fahre die Kombination Shimano GRX 11-fach Schalwerk RD-RX812-GS mit XT M8000 Kassette 11-46z und Schaltung funktioniert 1a. Ideal für mein Gravel-Bike mit 1-fach Antrieb.
As I Spected
This is the lose link betwenn the american and japanesse brands. This is "the link" that allows you to enjoy the best of the two major brands. There is a lot of marketing saying that all the drive train are "systems", than you need all the same brand, and bla bla bla. Well, this prove that you cand "craft" the drive train and get really interesting things. It really improved the shifting of my XTR RD with the XX1 11-42 cassette XD dome. Its a very good buy.
Great solution, but watch for compatibility issues.
Not compatible with 2013 XTR rear derailleur. Your derailleur must have an 8mm bolt. Check the website for more details.
