Every detail of the 11-speed X1 rear derailleur is engineered for smooth, reliable shifting action—from the larger upper pulley offset to the 12-tooth X-Sync pulley wheels. By eliminating unwanted chain movement, X-Horizon shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with Cage Lock technology, wheel removal and installation are easier than ever.

X-Horizon design reduces shift force, ghost shifting and chain slap
Q: What is the difference between this derailleur and the Type 2.1?
A: Type 2.1 derailleurs have a fixed pin in the clutch housing that is not present in Type 2 derailleurs.
Q: Does this Derailleur have a short, medium, or long cage?
A: This derailleur has a long cage. SRAM only offers one cage length for its 11-speed MTB derailleurs (XX1, X01, X1, GX) because they are only designed to work in 1x11 systems with a SRAM 10-42 cassette paired with a 1x crank.
