SRAM XX1 Eagle 6-piece groupset is a flagship mountain bike propulsion system. With an efficient, weather resistant and impressive shifting performance, the XX1 Eagle groupset is one of the best XC transmissions in the market. SRAM re-imagined their MTB crankset design to create a drivetrain that is lighter, stronger, stiffer and more durable.
This groupset aims to deliver a performance advantage to true competitors.

The SRAM XX1 groupset comprises of the six pieces detailed herein:
1. SRAM XX1 Eagle Dub Crankset with 34T X Sync 2 Direct Mount Chain Ring
This MTB crankset features hollow carbon fiber arms designed for XC and Trail riders. They are SRAM’s lightest carbon fiber arms. The X-Sync 2 chainring is shaped uniquely in order to maximize chain and wear retention. The XX1 Eagle Dub crankset is 10, 11 and 12 speed compatible and has to be used with SRAM’s Eagle chain for maximum performance. The crank arm length is 175mm, Chainring size is 34t, spindle diameter is 28.99mm, and the Pedal Spindle is 9/16 inches.
2. SRAM XX1 Eagle Chain, Hollow Pin 12 Speed 126 Links PowerLock
The 260 gram XX1 Eagle Chain has been re-engineered for 1x systems and the X-Sync 2 chainrings. It provides longer wear with less noise and less friction than previous SRAM chains. It features a flowlink design that eliminates the square edges on the outer plates to reduce friction and wear. The chain rivet contact area is recessed to allow high joining strength with no pin protrusion. The chain surface is treated with titanium nitride to reduce friction and enhance wear.
3. SRAM Eagle 10-50 12 Speed Cassette
The gold 12 speed XG-1299 cassette achieves maximum strength to weight ratio through its X-Dome machined 10-cog design. It weighs 352 gram and its 10-50 spread matches or exceeds the range of the heavier 2x drive trains. The tooth profiles allow for improved up and downshifting and better chain retention. It has also undergone a titanium nitride type of treatment to reduce friction and enhance tear. The SRAM Eagle 12 speed cassette fits the XD drivers used for the SRAM 10-42 11 speed cassettes.
4. SRAM XX1 Eagle 12 speed Rear Derailleur
The XX1 Eagle X-Actuation derailleur features an X-Horizon parallelogram structure, which minimizes the chain slap and maintains a gap with the Eagle cassette. This design results in fast and precise shifts with reduced shifter force. It also has a smoother torque curve for a more consistent feel and operation, with a Cage Lock feature for faster chain service and wheel changes. This gold XX1 Eagle derailleur is lightweight due to its titanium and aluminum hardware.
5. SRAM XX1 Eagle Trigger Shifter
This gold 12-speed trigger shifter features ball bearings at the rotation interface. This structure allows for a smooth-feeling and durable trigger shifter. It weighs 124 grams and is specific to the 1×12-speed Eagle drivetrain from SRAM. It also features X-actuation for extremely precise shifting across wide-ranging gear systems. The ergonomics are customizable via the pull lever with the adjustability, carbon fiber cover and a 2-position clamp.
6. SRAM Dub Bottom Bracket
The SRAM Dub bracket connects the carbon fiber crank arms and serves to protect the long-lasting smooth power application to the drivetrain. This bottom bracket has been engineered for better crankarm compatibility, element protection, durability and strength. The SRAM XX1 Eagle 6-piece group set enables you to upgrade your drivetrain to the 1×12 SRAM Eagle system.
It offers a 500 % gear range all while maintaining the simplicity of the 1x system. This group set ensures seamless shifts across the massive range and a super-efficient feel. Its standout feature is this shifting quality that is maintained even in the filthiest conditions.
