The RoadLink™ derailleur hanger extension is a unique patent-pending 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 40 T cassette. Easily installed in less than 5 minutes by any home mechanic!

Notes: Always adhere to manufacturer's published derailleur tooth capacity specifications. RoadLink is not required for 11-32 10-speed and 11-speed.
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.
7.9mm max dimension is controlled by the Shimano spec, but a few derailleur hangers don't meet the spec. You can file a bit of the bottom " tang" of those derailleur hangers to install the RoadLink.

This saved my drivetrain! It helped me to properly associate a 9 speed MTB cassette with a Deore road 9s rear derailleur. Easy setup and the derailleur is about 25mm lower than before, allowing accurate gear transitions.

Habs noch nicht probiert. Erst beim Öffnen des Pakets ist mir aber aufgefallen, dass bike-components eine wichtige Info hier leider nicht erwähnt:

Auf der Verpackung des RoadLinks steht
"Up to 11-40t cassette in 1x setup"
"Up to 11-36t cassette in 2x setup".

Diese Info fehlt im Beschreibungstext, ich habe natürlich 2x und mir eine 11-40Z Kassette dazubestellt :(

Hat dann schlussendlich ohne Probleme mit der 11-40Z Kassette funktioniert! Klare Empfehlung und wirklich ein sehr praktisches Teil

Ein super Teil und präzise gefertigt.
Mein kurzes Campagnolo Super Rekord 11-fach Schaltwerk bedient damit jetzt eine SARAM 11-36 Kassette

Für ein Sumrace 11-40 mit einer 9-fach XT Shadow nicht spezifiziert , funktioniert aber trotzdem einwandfrei.
