SRAM XX1 Eagle Type 3 X-HORIZON Rear Derailleur - max. 52 T. - 12-speed - Lunar

Occupying a new realm in shifting performance, the redesigned XX1 Eagle™ derailleur gives no-compromise racers and dream-bike builders a true top-tier option. The crisp, precise XX1™ shifting feel athletes rely on now features an updated cage geometry for improved chain management. Occupying its rightful place at the top of the Eagle™ ecosystem, the XX1 Eagle™ rear derailleur makes full use of the new 10-52t cassettes and is backwards compatible to also work with the 10-50t.

Highlights of the SRAM XX1 rear derailleur

• Updated cage geometry provides better chain retention and crisper shifting.
• Backwards compatible, works with 10-50t and new 10-52t cassettes.
• Eagle™ pulley technology provides greater efficiency, crisper shifting and quieter operation
• Carbon cage and lightweight hardware make it light and tough

Technologies

X-HORIZON™ - The X-HORIZON™ rear derailleur's 'straight parallelogram' design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.

X-ACTUATION™ - Developed specifically for SRAM X1, X-ACTUATION™ keeps shifting sharp and consistent across the entire cassette. Multi-adjustable trigger shifter. MatchMaker X compatible.

ROLLER BEARING CLUTCH™ - ROLLER BEARING CLUTCH™ rear derailleurs deliver maximum drivetrain stability-even through the most punishing terrain. With ROLLER BEARING CLUTCH™ technology, derailleur bounce and chain slap are eliminated without sacrificing precision.

CAGE LOCK™ - With CAGE LOCK™ technology in the rear derailleur, wheel removal and installation-as well as chain installation-becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.

X-SYNC™ - SRAM X-SYNC™ provides the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1X™ drivetrain.
