March 09, 2014 – Relentless — To be the best. It’s why you ride. It’s why we build components. The perfect combination of precision and brute force. No obstacles stopping us. No limitations slowing us down. Ours is a relentless pursuit: to make the climb shorter, the trail smoother, the turn tighter, the descent faster. To give you the strongest, lightest, quickest bike on earth. To be the best.

ONE. AND ONLY
The SRAM 1X™ drivetrain carries on the tradition of our championship-winning philosophy—all the way down the mountain. The setup is simpler. The drivetrain is lighter. And the shifting is fast but solid. Bottom line: SRAM 1X™ is the right one for any terrain, every time.

RELENTLESS.

SRAM 1X™ Technology

Single-minded pursuit.

Performance, Simplicity, Durability, and Lightweight. The SRAM 1X™ drivetrain philosophy focuses on optimizing how components work together—crank to chain ring, chain ring teeth to chain, shifter to derailleur, derailleur to cassette and cassette to wheel. SRAM 1X™ drivetrains are complete drivetrains for all types of riding.

X-SYNC™
SRAM X-SYNC™ 1X chain rings provide the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1X™ drivetrain.

HARD CHROME™
The XX1 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 XX1 chain lasts longer and is just as strong.

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 constant chain gap across all gears.

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™ technology eliminates derailleur bounce and chain slap without sacrificing precision.

X-ACTUATION™
Developed specifically for SRAM 1X™, X-ACTUATION™ keeps shifting sharp and consistent across the entire 10- to 42-tooth cassette.

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.

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.

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.

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.

SRAM X01 DH

Beyond Gravity
Every descent rewrites the laws of gravity. Every mountain pushes you further. Engineered in Germany, SRAM X01 DH delivers quicker shifting, smarter gear steps, and more precise chain management. Featuring SRAM’s 7-speed X-HORIZON™ rear derailleur and X-DOME™ MINI BLOCK™ cassette, the X-SYNC chain ring, and the X-ACTUATION™ trigger shifter, it’s the integrated SRAM 1X™ drivetrain for complete control. Made for gravity athletes. Proven by champions. And now available to every rider. X01 DH. GO BEYOND.
