Wolf Tooth Goatlink 11s Derailleur Hanger

The GoatLink 11 hanger extension offsets the position of your 11-speed Shimano mountain bike rear derailleur allowing you to be able to run a wider range cassette while improving performance.This project began with the desire to run 11-speed Shimano derailleurs and shifters with SRAM 10-42t XD cassettes. Granted the combination can work without modification - but performance wasn´t quite what we´d expect from Shimano and SRAM´s finest.When used with a 10-42t cassette, the GoatLink 11 re-positions SLX M7000, XT M8000 and XTR M9000 rear derailleurs such that free chain length between the cassette and the top derailleur pulley is within 1% of what Shimano intended while cassette tooth engagement in the smallest cog is improved by 27%.Knowing that certain situations call for a range beyond that provided 10-42t or 11-42t cassettes, we tweaked the GoatLink 11 to also significantly improve Shimano 11spd rear derailleur performance with extended-range like the Wolf Tooth GCX44 modified 10-44t XX1 or X01 cassette.Features:- Same ergonomics and reliability of Shimano shifters and derailleurs- Gear range, simplicity and quietness of SRAM 1x11 drivetrain- High-performance and lightweightCompatibility:- Cassette: Compatibility- 11-40: Not Required- 11-42: Not Required- 11-45: GS/SGS Derailleur- 11-46: GS/SGS Derailleur- 10-42: GS/SGS Derailleur- 10-44: GS/SGS Derailleur (Wolf Tooth GCX44)
