A 12-speed rear derailleur with a long SGS cage, designed for 10–51T cassettes. The SHIMANO SHADOW ES design helps stabilise the chain and reduces the derailleur’s contact with obstacles.
Features and specifications
- Low profile: SHIMANO SHADOW ES technology reduces the derailleur’s forward-facing surface and the chance of contact with rocks and roots.
- Robust construction: wide links and large pulleys increase durability and reduce dirt ingress.
- Chain stabilisation: the SHIMANO SHADOW ES dual-spring design increases chain tension to help keep the chain in place.
- HYPERGLIDE+: fast shifting under load, durability and smooth operation.
- Fast and precise shifting under load.
- Robust construction with a flat stabiliser.
- Steel cage.
- Long SGS cage for 12-speed cassettes with 10–51T sprockets.
- Mounting: direct mount (conventional).

Technologies
SHADOW ES – a low-profile design that reduces the forward-facing surface of the rear derailleur. This eliminates protruding edges that could catch on rocks or roots.
HYPERGLIDE+ – a cassette and chain system for mountain bike drivetrains, designed for fast, efficient and smooth shifting in any terrain. The system selects the optimal shift timing and helps adapt to rapidly changing terrain. According to Shimano, shifting time is reduced by one third compared with the previous HG system.
