The 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, made by Lindarets and Wolf Tooth, re-positions 10-speed Shimano Shadow+ Rear derailleurs to the optimal location when using the GC 40T and GC 42T cassette expanders.

 

Compatibility

  • Compatible Shimano Shadow+ 10-speed rear derailleurs (clutch type ONLY) 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.  Here is how to take that measurement:           

  • You will NEVER need a longer b-screw with the GoatLink
  • Improvements with the GoatLink*
    • Chain wrap at 11t (effects cassette life): 
      • 40t:  Improved by 69%
      • 42t:  Improved by 53%
    • Free chain length at 11t (effects shifting precision):
      • 40t:  Improved by 25%
      • 42t:  Improved by 19%

    *Due to variations in derailleur hanger geometry, chainstay length, chainring size, B-screw adjustment, and suspension configuration, individual results will vary slightly.
