SRAM Eagle™ - An integrated drive system
SRAM Eagle™ drives are 1x drives which have been developed as an integrated drive system for optimum performance. Eagle™ drives have been designed, tested and proven to be the lightest, most powerful and durable systems for any rider on any trail. It's the simplest, trouble-free drive system ever made by SRAM, and gives you the freedom to combine it with any component within the expanded Eagle ecosystem.
SRAM XX1 Eagle™ Rear derailleur 12-speed
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
XG-1299 Eagle Cassette Range of Dreams
Whether for prized race machines or the build of their dreams, the XG-1299 cassette is the ultimate, giving riders unprecedented 520-percent range thanks to the new 10-52 tooth-span. Stronger racers are now free to choose larger chainrings for more top-end speed, without sacrificing climbing range. More time is spent higher up in the cassette where athletes power transfer is most efficient and wear is minimized. Featuring the industry’s strongest X-Dome™ architecture and proven XD™ driver body, it’s also backwards compatible to give riders even more Eagle™ upgrade options for their current bikes. With multiple Olympic, World Cup and World Championship titles, it also matches up perfectly to XX1 Eagle AXS™ enabled componentry.
Stronger riders can increase chainring size for speed, without sacrificing climbing.
Provides a massive 520-percent gear range.
XD™ Driver Body compatible.
10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 52 tooth.
SRAM XX1 Eagle™ Trigger Shifter 12-speed
Experience the performance and feel of the XX1 Eagle™ shifter, and you quickly realize there must be something special going on inside this little nerve center. And there is, to the tune of time-tested and race-tested X-ACTUATION™ technology, adjustable lever positioning and that buttery feel of XX1 Eagle™. Featuring a carbon trigger and cover for our lightest weight – the trigger glides on precise, near frictionless sealed cartridge bearings. Thanks to Eagle™ Colorsystem and the XX1 Eagle™ master group colorway, all-new looks let creativity soar.

Features of the SRAM XX1 Eagle Trigger Shifter
XX1 Master colorway matches all cassettes and chains as part of Eagle™ Colorsystem.
Adjustable carbon trigger and cover reduce weight.
Discreet clamp or Matchmaker-X™ compatible.
SRAM XX1 Eagle™ Chain 12-speed
It might look normal from the outside, but the engineering inside this incredible new chain design that makes possible a gear range previously found only in 2-chainring drivetrains. And it's also the biggest contributor to the Eagle™ drivetrain's ultra-smooth, precise, durable and quiet performance. The Eagle™ chain's links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear on chainrings and cassette cogs. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength. HARD CHROME™ technology extends the chain's optimal performance life, and a Titanium Nitride coating on the Gold and Black models decreases corrosion and further reduces friction.
Groundbreaking new chain design and technology
The Eagle™ chain has been completely re-engineered, and is produced with new manufacturing technology.
All-new Eagle™ PowerLock® chain connector with FLOWLINK™ technology provides better chain-guiding and increased longevity.
The XX1 Eagle™ chain is on of the quietest, strongest and most wear-resistant chain in the world.
Unique features and design also provide significantly improved wear resistance on Eagle™ cassettes and rings.
