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.

- The RoadLink is optimized for use with ten or eleven-speed 11-36t and 11-40t cassettes.
- 11-42 or 10-42 setups are not supported.
- Works with all 10-11 speed Shimano and SRAM Road Derailleurs.
- Best used with Single or Double Setups - see manufacturer's site for more details.
