The Wolftooth RoadLink DM derailleur hanger extension is a unique patent-pending device that offsets the position of your Shimano Ultegra R8000 und Dura Ace R9100 road derailleur to make it possible to run a wide-range mountain bike style cassette. It is an ideal solution for riders looking to convert their road, gravel, cyclocross, or commuter drivetrain bike to attain the simplicity and reduced weight of a single front chainring but without giving up the gear range of a double. It is also great for riders with double chainring bikes that want lower gearing for those ultra steep climbs. It does not compromise the shifting in the smaller cogs of the cassette but yet it enables the derailleur to work with as large as a 40T cassette.
Easily installed in less than 5 minutes by any home mechanic!
The RoadLink DM adaper installs in minutes, is optimized around Shimano eleven-speed road derailleurs and shifters, but works well with SRAM cassettes. It can be used with single or double chainrings. Here is a list of recommended applications:
11s Cassette Compatibility:
- 11-32: Not Required (GS medium cage rear derailleur works)
- 11-36: Single or Double Chainring
- 11-40: Single or Double Chainring (front rings can be no more than 14 teeth different e.g. 48-34)
- 11-42: Single
- 10-42: Single - improve performance but not to factory levels
The RoadLink™ mounts only to standard derailleur hangers.
2-speed cranks are only compatible with GS (medium length) rear derailleurs. 3-speed cranks are not compatible with RoadLink DM.
