Wolf Tooth GoatLink 11

Wolf Tooth GoatLink 11 is a precision-machined derailleur hanger extension that repositions compatible Shimano 11-speed mountain rear derailleurs to improve shifting performance with wider-range cassettes. Designed for riders who want expanded gearing without sacrificing Shimano ergonomics, the GoatLink 11 refines derailleur geometry for smoother operation and better chain control. Originally developed to optimize Shimano 11-speed derailleurs with SRAM 10-42T XD cassettes, the GoatLink 11 adjusts derailleur position so that free chain length and chain wrap more closely match Shimano’s intended design parameters. The result is improved small-cog engagement and more consistent shifting across extended-range setups. It also enhances performance when paired with select 11-speed extended-range cassettes, including modified 10-44T options. By fine-tuning derailleur placement, the GoatLink 11 improves chain wrap and reduces unsupported chain in the smallest cog, helping maintain drivetrain precision under load. Important: The GoatLink 11 increases derailleur clearance for larger cassette cogs but does not increase derailleur capacity. Always confirm your derailleur’s total capacity before expanding gear range.
