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. The RoadLink DM (Direct Mount) is the RoadLink that fits Shimano's R8000-generation Ultegra and R9100-generation Dura-Ace rear derailleurs. 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 expec for their road, commuter, gravel, and touring bicycles. Compatibility: * Fits only Shimano R9100-generation Dura-Ace and R8000-generation Ultegra rear derailleurs * 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 * See plot for chain wrap and free chain impacts * Does not change the derailleur'scapacity. Review and understand Wolf Tooth's RoadLink Tech Page before purchg or installing! Tech Specs: * 20g weight (8g more than stock) * CNC machined from 6061-T6 aluminum with stainless steel bolt * Type II anodized in black * Designed and manufactured in Minneapolis, MN USA
