It seems like as soon as a new group is launched, riders are already looking for ways to maximize its gearing. Fortunately, for those so inclined to reach for bigger cassettes, companies like Wolf Tooth Components are always looking for solutions. This time it’s the RoadLink DM – a new version of their popular GoatLink which makes Shimano R9100/R8000 derailleurs play nice with bigger gears.
Like the originals, the RoadLink DM is slightly longer than the stock link and effectively repositions the rear derailleur to allow for larger cassettes. Key to the design is the ability to maintain what they consider factory levels of chainwrap and shifting performance with most cassettes.
This particular version is specifically for the Shimano R9100 Dura Ace or R8000 Ultegra rear derailleurs and is direct mount to the derailleur, not the hanger. WTC points out that this is compatible with standard derailleur hangers only, not direct mount hangers. Weighing in at 20g, the link is about 8g heavier than stock thanks to its added length, and is CNC machined from 6061-T6 aluminum with stainless steel hardware. Of course, it’s made in the USA by WTC in Minneapolis, MN, and is black with a Type II anodizing.
WTC says that the RoadLink DM is optimized for use with 11-36t, 11-40t, and 11-42t 11-speed cassettes. It will also work with 10-42t 11 speed cassettes, but they point out that with this cassette it will improve the performance, but not to what they consider factory levels.

The links sell for $27.95 each and are available now.
