Tuotteen kuvaus
SRAM DUB™ technology features a better-engineered bottom bracket and a new spindle design. Together, these allow for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of durability.
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.
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.
X-ACTUATION™
Developed specifically for SRAM 1x™, X-ACTUATION™ keeps shifting sharp and consistent across the entire cassette.
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.
EXACT ACTUATION™
When we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel : derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up and it stays that way.
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.
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®
SRAM chain engineers developed PowerLock® as a tool free, sure, and consistent way to connect our chains. While PowerLock® does not require special tools for install, the especially tight tolerances of 10-, 11- and 12-speed drivetrains mandate that each PowerLock® is good for a one-time application only.

DUB™
Forward thinking and backwards compatible DUB™ BB/Crank technology is the workhorse without restraint. Designed for the most discerning pros. And riders who set it and neglect it. DUB™ is compatible with all major bottom bracket standards. Offering better sealing than ever before, without having to make compromises to fit all frames. Yet it opens the door for a new crank spindle for the world’s all-time lightest crank set. It’s a new approach that embraces the old. And it’s about time.
After extensive research, Sram unifies the diameter of bike crankshafts and inner bearings to 28.99mm from 2018. The new bearing technology DUB (Durable Unifying Bottom Bracket) sets new standards from now on.
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.
