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.

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.

28.99mm Axle Diameter – Stiffer than GXP yet lighter than BB30.

DUB™ Technology – Compatible with all existing BB sizes and frames.

Forged Aluminum – 6000 Series aluminum, strong and light enough for any ride.

X-SYNC™ 2 Chainring – 32 tooth steel narrow wide chainring for max chain retention and durability.

MatchMaker X Integrated – The MatchMaker X clamp is more than just a clamp. It’s like having Martha Stewart tidy up your cockpit. Since each clamp accepts up to three controls, you can put everything from your XLoc suspension lockout, your SRAM shifters and AVID brake levers as well as your Reverb XLoc remote, all on two clamps. Short of genetically engineering longer thumbs, it’s the ideal way to put everything within easy reach. Just like Martha would.

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

ZeroLoss™ – ZeroLoss simply means, well, zero loss—when you push on the lever, for an upshift or down shift, the cable is engaged instantly—zero loss of movement. There is no middle-ground where you're waiting for the shift to come. Gear changes are instant and precise.

11-50 Tooth Gear Range – A perfect fit for any ride with optimized gear steps across entire range.

PowerGlide II – Cassette technology optimized for offroad. More reliable. More durable. Better performing, thanks to an optimal tooth profile and shift ramp design for quick and positive index shifting. Go climb a mountain.

Steel and Aluminum – 8 lightweight, stamped steel cogs and 4 high-strength steel cogs pinned onto an aluminum spider.

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.

PowerLock® Quick Link – SRAM chain engineers developed PowerLock® as a tool free, sure, and consistent way to connect chains.

X-Sync™ 2 – 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.
