Wolf Tooth Goat Link 10 speed

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.
