This project began with the desire to run 11s 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 M8000 XT and M9000 XTR rear derailleurs such that free chain is within 1% of what Shimano intended while engagement is improved by 27%.

But we didn't stop there.  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 11s rear derailleur performance with extended-range like the Wolf Tooth GCX44 modified 10-44t XX1 or X01 cassette.

So now you too can have it all:  ideal performance from 10-42t XD cassettes and wide-range capability for bigger days.
