Details / Wolf Tooth Components Lindarets GoatLink Shimano Direct Mount Rear

A Wolf Tooth GoatLink is simply the fastest route to improved wear and long-term shifting performance on wide-range 1x10 drivetrains using the Shimano Shadow+ rear derailleurs.  The GoatLink re-positions 10 speed Shimano Shadow+ rear derailleurs to the optimal location when using the GC40 and GC42 cogs.


  • Compatible Shimano Shadow+ 10 speed rear derailleurs have a Direct Mount link (including spacer, if so equipped) or B-pivot knuckle with a thickness of 7.9-8.1mm.  Shimano changed to this sometime in 2013.  Very early Shadow+ rear derailleurs have a thinner link and are not compatible. 

  • The GoatLink is optimized for use with Wolf Tooth’s 40- and 42-tooth GCs and all sizes of Drop-Stop chainrings- but will work with any 11-40t or 11-42t ten-speed cassette.  

  • Direct Mount-native frames and SRAM rear derailleurs are not supported.  


  • You will NEVER need a longer b-screw with the GoatLink
