The Wolf Tooth Wolf Cage Derailleur Cage allows you to run wide-range 11-speed cassettes on your existing derailleur whilst also improving shifting quality and drivetrain longevity. Super simple to install and beautifully machined, this is perfect for gravel riders, tourers and MTB tweakers.
This modified inner derailleur cage comes with an eccentric upper jockey wheel and is perfectly primed to upgrade existing 11-speed Shimano rear derailleurs, unlocking the potential to run up to 11-49 cassettes. Pared with a Wolf Tooth GC 49 sprocket, you’ll be able to make it up even the most gnarly gradients with ease.
Because only the inner part of the cage needs to be changed, installation of the Wolf Tooth Derailleur Cage is super simple and can be completed in several minutes – no need to break the chain or remove your existing rear derailleur from your bike.
- The Wolfcage is compatible ONLY with Shimano 11-speed rear derailleurs. Be sure to select the right cage length. Here are the pulley centre to centre distances for each cage type so you can be sure to order the right one (GS is the "medium cage" and SGS is "long cage" length):
- XTR 9GS - 84mm (same cage as M8050 XT Di2).
- XT 8GS - 88mm
- XT 8SGS - 107mm
- XTR Di2 M9050 GS - Not supported
- XT Di2 M8050 GS - 84mm - use the XTR 9GS
