Wolf Tooth’s new RoadLink DM (Direct Mount) allows Shimano R9100/R8000 derailleurs to work with bigger cassette cogs resulting in a broader gear range for touring or bikepacking…

Posted by Logan Watts

The original RoadLink derailleur hanger extension offsets the position of a road derailleur and enables it to work with a wide-range mountain bike style 36 or 40t cassette. RoadLink is often used for converting road or cyclocross drivetrains to a single front chainring without sacrificing too much gear range, or to add a granny gear that’s tolerable on steep hills when touring or bikepacking with an additional load.

Just released, the RoadLink DM (Direct Mount) is the latest in Wolf Tooth’s RoadLink/GoatLink line of derailleur optimization products. The DM version fits Shimano’s current generation R8000 Ultegra and R9100 Dura-Ace rear derailleurs. Like Wolf Tooth’s MTB-focused GoatLink, the RoadLink DM is slightly longer than Shimano’s stock Direct Mount derailleur link and effectively moves the rear derailleur outward to allow for a larger cassette. And, according to Wolf Tooth, RoadLink and GoatLink can even improve shifting. Each Wolf Tooth RoadLink and GoatLink are designed to maintain near-factory levels of chain wrap and shifting performance with the cassettes specified.

    This is so timely for me. I have a trip coming up in May and have been pondering whether to replace my existing cassette with a larger spread. I was worried that I would need to replace my derailleur with a long cage. Now I know what to do. Thanks!

    I’m curious would this enable a regular short cage rear derailleur to work on a larger cassette?
