Wolf Tooth Components, Goatlink 11, Shimano MTB 11

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.

• Same ergonomics and reliability of Shimano shifters and derailleurs

• Gear range, simplicity and quietness of SRAM 1x11 drivetrain

• High-performance and lightweight

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 GCX 44t modified 10-44t XX1 or X01 cassette.
