RoadLink Rear Derailleur Adapter - black/universal
Item number: 64179

Adding a few gears: the RoadLink rear derailleur adapter by Wolf Tooth Components

Wolf Tooth's RoadLink™ rear derailleur adapter is a unique device that shifts the position of your Road derailleur so that you can ride a wide range MTB cassette with it. The ideal solution for riders who want to equip their Road, Gravel, Cyclocross or commuter bike with an uncomplicated, light 1x drivetrain, but who do not want to do without the wide gear selection of a 2x drivetrain. Also for riders with 2x drivetrains who need even lower gears for ultra steep climbs. The RoadLink does not interfere with the shifting of the smaller sprockets of the cassette, but allows the rear derailleur to work with a cassette up to 40 teeth. The RoadLink is also very easy to install; experienced home mechanics only need 5 minutes.

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.
