First Look: SRAM X01 DH Drivetrain

Components News

We knew it was just a matter of time until X01 spread its wings in the Downhill Racing arena. Already a favorite among many gravity oriented racers, SRAM made several improvements to make 1x stronger, quicker and more precise.

Read on see if this new drivetrain is for you.

SRAM 1X™ Technology

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 7-Speed

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.

SRAM X-SYNC™: A Developing Story

More than a decade ago, SRAM’s German engineers decided to go head-to-head with a fundamental frustration of biking—how to keep the chain on the ring. They began by looking at dual-drive solutions concocted for urban riders whose chains would disengage as they pedaled along bumpy European roads. These dual-drive models offered a simplified, focused approach that could make sense away from the city streets, too. The engineers were inspired. Ideas started to fly. Designs followed. Field tests. Frustrations. They learned lessons—for instance, that side-to-side movement (not up-and-down) was the most frequent cause of a disconnected chain.

The engineers now had a single goal in mind: to create the perfect MTB chain ring—a ring that wouldn’t drop the chain in any conditions or under any circumstances. This led to the unprecedented thick-thin tooth shape. To optimized square tooth geometry. To mud recesses that kept the chain clean and moving. All focused on the dynamic bike platform. As SRAM lead engineer Frank Schmidt puts it, “We further developed it until we reached perfect chain control.” The original narrow-wide chain ring is now the perfect MTB chain ring for riders who never compromise. X-SYNC™—ONLY BY SRAM.

NEW XG-795 X01 DH MINI BLOCK™ 7-speed Cassette

The MINI BLOCK™ X-DOME™ 7-speed cassette is engineered for the optimized gear steps that downhill riders want. Featuring 10–24 gearing with two-tooth steps, this technology eliminates the need for double/triple shifts to get in the gear you want. And because it’s so compact, it’s also light—the lightest cassette in existence. Compatible with any XD wheel, MINI BLOCK™ X-DOME™ technology integrates flawlessly with your SRAM 1X™ drivetrain. With durable JET™ black finish, the cassette looks as tough as it performs—ride after ride.

Features/Benefits:

  • Larger jumps between gears eliminate the need for double/triple shifts to get in the gear you want. (10-12-14-16-18-21-24)
  • Less cogs allow faster transition from starting gear to high gear. Half as many shifts to get from 24-10 versus a normal 10-speed 26-11
  • Larger gear range, 10-tooth cog opens up high end and allows smaller rings for ground clearance
  • Lightest cassette. Ever.
  • More rear wheel clearance around spokes
  • 2-tooth steps are safer in shifting than 1-tooth steps under big loads
  • Currently fits any XD™ compatible wheel and driver body

    And so it begins…back to 7 gears sold to us at insane prices.

    Don’t get me wrong, I would kill for this with a more all-round spread, but not for this costs.
