Wolf-tooth Wolf Tooth GoatLink Derailleur Hanger Extension For 10S Shimano Shadow RD+ Derailleur

The Wolf Tooth GoatLink is simply the fastest route to improved wear and long-term shifting performance on wide-range 1×10 drivetrains using the Shimano Shadow+ Rear derailleurs. The GoatLink, made by Lindarets and Wolf Tooth, re-positions 10-speed Shimano Shadow+ Rear derailleurs to the optimal location when using the GC 40T and GC 42T cassette expanders.

Features:

• Weight: 19 g.
• Material: 6061 aluminum.
• Included: stainless steel bolt.
• Torque: 8-10 Nm.
• Made in the USA.

Compatibility:

• Compatible Shimano Shadow+ 10-speed rear derailleurs (clutch type ONLY) have a Direct Mount link (including spacer, if so equipped) or B-pivot knuckle with a thickness of 7.9-8.1mm. Shimano changed to this sometime in 2013. Very early Shadow+ rear derailleurs have a thinner link and are not compatible.
• The GoatLink is optimized for use with Wolf Tooth’s 40- and 42-tooth GCs and all sizes of Drop-Stop chainrings – but will work with any 11-40t or 11-42t 10-speed cassette.
• Direct Mount-native frames and SRAM rear derailleurs are not supported.
• You will NEVER need a longer b-screw with the GoatLink.

Improvements with the GoatLink*:

Chain wrap at 11t (effects cassette life):

• 40t: Improved by 69%.
• 42t: Improved by 53%.

Free chain length at 11t (effects shifting precision):

• 40t: Improved by 25%.
• 42t: Improved by 19%.

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