The Wolf Tooth GoatLink derailleur hanger extension is simply the fastest solution to improve long-term lifespan and shifting performance on 1x10 wide-range drivetrains using Shimano Shadow RD+ rear derailleurs. Made by Lindarets and Wolf Tooth, it repositions Shimano Shadow RD+ 10-speed rear derailleurs to the optimal position when using GC 40-tooth and GC 42-tooth cassette sprockets.

DETAILS:

• Weight: 19 g.
• Material: 6061 aluminium.
• Stainless steel bolt included.
• Torque: 8–10 Nm.
• Made in the USA.

COMPATIBILITY:

• Compatible Shimano Shadow RD+ 10-speed rear derailleurs (clutch type only) have a Direct Mount link (including spacer, if applicable) or a B-pivot link with a thickness of 7.9 to 8.1 mm. Shimano changed to this in 2013. Early Shadow RD+ rear derailleurs have a thinner link and are not compatible.
• The GoatLink is optimised for use with Wolf Tooth GC 40- and 42-tooth sprockets and all Drop-Stop chainring sizes, but will also work with any 10-speed 11-40 or 11-42 cassette.
• Native Direct Mount frames and Sram rear derailleurs are not supported.
• You will never need a longer B-screw with the GoatLink.
