Goatlink

The Lindarets x 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 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:            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.   Complimenting Products: GC40 and GC40s cassette extenders Drop stop chainrings Technical Details: 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 at 11t (effects shifting precision): 40t:  Improved by 25% 42t:  Improved by 19% Stainless Steel mounting hardware included Material 7075-T6 Manufactured in Minnesota, USA Weight:    19g
