Wolf Tooth RoadLink Direct Mount for Shimano R8000/R9100 Rear Derailleurs when using Wide-Range Cassettes

The Wolf Tooth RoadLink derailleur hanger extension offsets the position of your R8000 and R9100 road derailleur, allowing you to use a wider mountain bike cassette. This is perfect if you want to switch to a 1x setup with ease.If you prefer the simplicity of a single chainring upfront or need lower bail-out gears on your double without altering your current groupset or compromising shifting performance, then the RoadLink is the solution for you.**Compatibility**- Fits Shimano R9100-generation Dura-Ace, R8000-generation Ultegra, and R7000 105 rear derailleurs- Fits standard derailleur hangers only- Direct mount derailleur hangers are not supported.
