The Shimano XTR 12-speed groupset is at the top of the heap in terms of mountain bike components. This rear derailleur is made to work with a 2x12 double chainring setup. The derailleur manages the system incredibly well. It decreases its tension at lower gear positions to prevent high chain tension and unwanted friction. 13T pully wheels add to the stability and friction to withstand the full force of pedaling on a difficult trail. A bumper is featured at the rear derailleur cage to enhance that durability and smooth feel. The Shadow RD+ clutch system provides extra chain retention on all terrain which avoids pesky chain slap. The Shimano XTR M9120 Rear Derailleur is an excellent way to promote the smoothest shifting in a lightweight and durable component.
