Wolf Tooth GoatLink 11
Wolf Tooth GoatLink
What Is It?
The Wolf Tooth GoatLink 11 is a derailleur hanger extension designed specifically for certain 11-speed Shimano mountain bike rear derailleurs. It repositions the rear derailleur to improve shifting performance when using larger-range cassettes, allowing riders to run bigger sprockets without immediately replacing their derailleur.
How It Works
The GoatLink 11 installs between the frame's derailleur hanger and the rear derailleur.
By changing the derailleur's mounting position, it:
- Moves the derailleur into a more optimal position relative to large cassette cogs.
- Improves guide pulley clearance on larger sprockets.
- Increases chain wrap and reduces unsupported chain length in many wide-range cassette setups.
- Helps maintain better shifting performance than simply winding out the B-tension screw.
Important: The GoatLink 11 provides clearance for larger cassettes but does not increase derailleur capacity. Total drivetrain capacity limits still apply.

Who Is This Best Suited For?
XC & Trail Mountain Bikers
Riders using Shimano 11-speed drivetrains who want easier climbing gears without upgrading to a newer drivetrain.
Bikepackers
Ideal for riders carrying gear and needing wider-range gearing for steep climbs and long-distance adventures.
Budget-Conscious Upgraders
A cost-effective solution for extending cassette range instead of purchasing a new derailleur and drivetrain.
Riders Mixing Shimano and XD Cassettes
Originally developed to optimize Shimano 11-speed derailleurs with SRAM-style 10-42T and 10-44T XD cassettes.
