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 1×11 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 combinationcanwork 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 11re-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 10-44tXX1 or X01 cassette.

NOTE:GoatLink 11 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 derailleurs capacity before attempting to expand its gear range.

Compatibility

11-45 GS/SGS Derailleur
11-46 GS/SGS Derailleur
10-42 GS/SGS Derailleur

Other notes:

• The GoatLink 11 is compatible with SLX M7000, XT M8000 and XTR M9000 series 11-speed Shimano rear derailleurs.
• Not compatible with Shimano RD-RX812 or RD-RX817 due to the 31T capacity limitation.
• The GoatLink 11 mounts only to standard derailleur hangers.
• Double chainrings (2x) is supported and requires a long cage (SGS) rear derailleur with no more than a 12t difference in front chainrings (with an 11-46t cassette).
• Triple chainrings are not supported.
• Direct Mount native frames and SRAM derailleurs are not supported.

Improvements with the GoatLink 11*:

10-42t Improved by 99%
Free Chain in bottom cog (unsupported chain – shorter is better and will increase shifting precision):

10-44t Improved by 32%
10-45t Improved by 28%
11-45t Improved by 36%
11-46t Improved by 32%
9-44t Improved by 26%

Chain Wrap in bottom cog:

10-42t Improved by 27%
10-44t Reduced by 9%
10-45t Reduced by 7%
11-45t Reduced by 8%
11-46t Improved by 12%
9-44t Reduced by 8%
Summary in plot form – movement towards the red X is in the direction of goodness (more chain wrap and less free chain)

*Due to variations in derailleur hanger geometry, chainstay length, chainring size, B-screw adjustment, and suspension configuration, individual results will vary slightly.
