One. Technology.

X-Glide™ 2

X-Glide™ is next generation of SRAM X-GLIDE™ technology optimized for the EAGLE™ 12-speed cassette. It provides quick, precise, power-on shifting performance throughout the gear range, and increases chain retention on larger cogs.

Flow Link™

Ultra-smooth chain inner-plates are completely devoid of square edges, resulting in a chain that engages the cassette and chainring with far less friction, for quieter performance and better wear life. The design allows a narrower overall profile that can withstand greater angles, and also allows for a flatter outer-plate, which means more consistent chain riveting and enhanced overall strength.

Carbon Tuned™

Strength and stiffness where you need it, lightweight like you want it. Proprietary SRAM carbon lay-up design increases thickness and stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength.

X-Sync™ 2

X-SYNC™ 2 Eagle is the next evolution of SRAM X-SYNC™ technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC EAGLE™ design reduces friction and the accumulation of mud, grit and grime.

X-Horizon™

This 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 consistent chain gap across all gears.

X-Sync™

A CNC-machined, “wide tooth, narrow tooth” pattern is repeated around the entire chainring, perfectly mirroring the chain’s inner and outer links for maximum control.

X-Dome™

X-DOME technology creates an incredibly lightweight, precise and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.

Roller Bearing Clutch™

Roller Bearing Clutch technology eliminates derailleur bounce and chain slap without sacrificing precision.

MINI CLUSTER™

The MINI CLUSTER™ hybrid cassette construction combines three small cogs that are CNC-machined out of a single block of billet steel with an additional eight cogs that are individually pinned together. The result: a cassette that’s light, durable and equipped with a 10-42 gear range that’s a perfect fit for any ride.

Cage Lock™

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

Just push the cage forward—creating slack—and lock it in place. The chain stays perfectly loose, letting the derailleur swing out of the way. When you’re ready to ride again, simply unlock the cage and go.

XD Driver Body™

XD™ is a cassette driver body design that allows the use of a 10-tooth small cog and provides an improved interface with the cassette.

Hard Chrome™

The SRAM HARD CHROME™ chain has four times the elongation (wear) resistance to our other chains. This is due to the new finishing process on the inner links and rollers. Push pin strength and ultimate strength are equivalent to our current chains. The HARD CHROME™ chain lasts longer and is just as strong.

X-Actuation™

Developed specifically for SRAM 1x™, X-ACTUATION™ keeps shifting sharp and consistent across the entire cassette.

Rolling Thunder™

Three rows of ball bearings provide zero friction or play—reducing the force needed to shift and promoting long-term performance under all weather conditions with Grip Shift.

JET™

With durable JET™ black finish, the cassette looks as tough as it performs—ride after ride. JET™ finish provides a higher level of corrosion resistance.

Speed Metal™

Full metal, 11-speed indexing keeps shifting crisp and precise with Grip Shift.

MINI BLOCK™

Light, strong and precise, the MINI BLOCK™ X-DOME™ cassette lets you bring the right kind of power to every ride. This 7-speed cassette designed for downhill features an optimized gear range that eliminates the need for double/triple shifts to get in the gear you want.

Jaws™

Once the Grip Shift shifter and grip interlock securely, forged aluminum clamps on either end reinforce the assembly by locking tightly to handlebar.

E-BLOCK™

E-BLOCK™ shifting technology is a fundamental redevelopment of external drivetrain shifting. On the E-BLOCK™ cassette, the chain has a defined link position on each cog. Cog architecture has been engineered to work with both inner and outer links of the chain, which allows extremely refined shifting for both inboard and outboard shifts. The result is precise and robust shifting performance in any situation, even with full motor support.
