Wolf Tooth RoadLink derailleur hanger extension

The RoadLink™ derailleur hanger extension is a unique patented device that offsets the position of your 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.


Features

  • The RoadLink™ is optimized for use with 10 or 11-speed 11-36t and 11-40t cassettes and work great with Wolf Tooth’s 40-tooth GC cassette extenders and Drop-Stop chainrings.
  • Double chainrings are only supported with GS (medium cage) rear derailleurs. You may need to change the front gearing so the rear derailleurs capacity is not exceeded.
  • The RoadLink™ mounts only to standard derailleur hangers, Direct Mount-native frames are not supported.
  • The RoadLink™ is optimized for the 10- and 11-speed Shimano road derailleur geometry. It also works very well with 9-speed road groups, all SRAM groups, and Campy derailleurs! One note is that with Campy it works best with cassettes up to 11-36.
  • Due to the lack of a clutch mechanism on Shimano road derailleurs, secondary chain retention (front derailleur or chain device) may be needed, especially for rough or off-road use.
