Since its introduction, the award-winning Wolf Tooth RoadLink has given riders the ability to easily increase the range of their Shimano road drivetrains while maintaining near-factory levels of chain wrap and shifting performance. Like the mountain-focused GoatLink, the RoadLink DM replaces Shimano’s stock direct mount link allowing you to relocate the derailleur to provide clearance for larger-than-stock range cassettes while maintaining chain wrap and improving shifting. The result—larger gear ranges that riders want and expect for their road, commuter, gravel, and touring bicycles. Compatibility Fits Shimano R9100-generation Dura-Ace, R8000-generation Ultegra, RX800 and RX805 Ultegra, and R7000 105 rear derailleurs in 1x configurations Optimized for use with GRX ultra wide range drivetrains when using the GRX 810 (RX810) rear derailleur paired to a 1x chainring configuration. Not compatible with 2x GRX drivetrains. Fits standard derailleur hangers only Direct mount derailleur hangers are not supported. These are not common and the stock b-link that the RoadLink DM replaces will not be present on bikes with a direct mount derailleur hanger Optimized for use with 11-36t, 11-40t, and 11-42t 11-speed cassettes Will improve performance with 10-42t 11-speed cassettes, but not to factory levels Does not change the derailleurs total chain wrap capacity.
