Goat Links replace the direct mount link or B-Pivot knuckle on Shimano Shadow + Derailleurs to optimise the derailleurs position when using larger cassettes or extended cogs.

10 Speed Information:

Why purchase a new drivetrain when you can increase the range of your Shimano 10-speed setup? The Goat Link compliments the Wolf Tooth Giant Cog for Shimano 10-speed drivetrains.

We recommend this item for riders who are using the GC extender cog with their Shimano 10-speed drivetrains. The Goat Link re-positions the derailleur optimising shifting and improving longevity.


  • The GoatLink will only work with Shimano Shadow+ (clutch) 10-speed rear derailleurs which use a Direct Mount link or B-pivot knuckle with a thickness of 7.9-8.1mm. Shimano made a running change in 2013, Shadow+ derailleurs purchased in 2013 and earlier will need to confirm fitment.
  • Direct Mount-native frames are not supported.
  • SRAM derailleurs are not compatible.


  • Eliminates the need for a longer b-screw.
  • Stainless Steel mounting hardware included.
  • 7075-T6 aluminium.
  • 19g

11 Speed Information:

The Goat Link 11 is optimised for using a 10-42 SRAM Cassette, with Shimano Derailleurs and Shifters.

It also provides advantages for anyone running a GCX 44 cog on their SRAM cassette too.

    The all time GOAT of derailleur extenders!

    Get ya big gears on with this sassy little link. Works well with a 11-46 10-Speed cassette and Shimano Shadow+ derailleur. Helps get my lazy arse up the hills! Crisp shifts and easy set-up. Stop ya moaning and get one.

    Pricey, but a nice birthday present for an M8000 Derailleur

    Swapped out for the standard direct mount screw on a m8000 long cage derailleur and now shifts into the dinner plate 50 tooth on an 11 speed sunrace cassette like a dream. The extra 10ish mm stretch out back this link provides over the standard shimano direct mount screw is a good upgrade if you dont want to pony up for the jump to 12 speed but still want to run a modern big boy cassette with the larger gearing range and maintain the butter smooth shifting up the top the way shimano intended it......

    Great design, a must have!

    Moving up to a 11-42T cassette from a 11-36T when completing a 1x conversation with a Deore 10 speed rear mech this has worked wonders. Great chain wrap, crisp shifts and zero shifting issues. Didn't even need to touch the b screw!

    XT 785 medium cage 10spd

    XT 785 medium cage 10spd rear deraileur and shifter + Sunrace 11-42 cassette. Goatlink added and everything works perfectly. Little expensive but cheaper then buying an all new 11 speed setup when going 1x up front!
