Product Description For Direct Mount compatible Shimano rear derailleurs: the RoadLink DM rear derailleur adapter by Wolf Tooth Components The award-winning Wolf Tooth RoadLink has enabled road cyclists to extend the gear spread of their Shimano Road drivetrain - while keeping capacity and shifting performance virtually unchanged. The RoadLink DM (Direct Mount) is a further development of the RoadLink, which works with the current Shimano R9100 Dura Ace, R8000 Ultegra and R7000 105 rear derailleurs. As with the MTB-specific GoatLink, the Wolf Tooth RoadLink DM rear derailleur adapter offsets the rear derailleur, creating a clearance for wide-range cassettes while maintaining capacity and improving shifting. The result? Wider gear ratios that riders need and expect for their road, commuter, gravel or touring bikes.
