Wolf Tooth GoatLink

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.

NOTE: GoatLink repositions your derailleur to provide clearance for larger cassette cogs but it does not increase derailleur capacity. It is critical to find and understand your derailleur’s capacity before attempting to expand its gear range.

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:

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