This derailleur expands the range with a single front chainring.
The clutch keeps the chain tensioned, even in rough terrain.
The derailleur's electric shifting system allows for very fast and smooth shifting.
The position under the cassette ensures good handling on mud and wet terrain.
With this derailleur you get the best technology Shimano has to offer.
This derailleur shifts very smoothly.
This derailleur is also very light.
Cons
This derailleur can only be used with a single front chainring.

This derailleur cannot handle a tooth larger than a 30. If you want to be bigger, you need the Ultegra R8000 long cage derailleur.
