X-SYNC™ Chain Rings

Engineered for downhill, the X-SYNC™ narrow-wide chain ring delivers complete control. Tall, square teeth, rounded chamfers and a thick-thin tooth geometry combine to engage the chain earlier—and never let it go. With multiple ring options available, you can match your gear range to your terrain, wheel size and riding style. And recesses at the base of the teeth get rid of mud so the chain remains in place no matter what conditions you’re up against.

• X-SYNC™ tall, square tooth design provides maximum chain control
• Sharp, narrow tooth profile and rounded chamfer edges help manage a deflected chain
• 30-, 32-, 34-, 36-, or 38-tooth single ring
• X-SYNC™ technology for all 10- and 11-speed systems, as well as new 7-speed systems
• CNC machined 7075, two- tone anodize
• Mud-clearing recesses for the inner chain links and rollers
• An integral component of the SRAM 1X™ drivetrain


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.

• 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

• JET™

NEW X01 DH X-HORIZON™ Rear Derailleur
The 7-speed X-HORIZON™ rear derailleur makes shifting smooth and reliable no matter where you ride. Engineered to maintain consistent chain gap across all seven gears, X-HORIZON™ eliminates vertical movement for faster shifting, reduced shift force and an end to ghost shifting. ROLLER BEARING CLUTCH™ technology and the 12-tooth X-SYNC™ pulley wheels hold the chain in place, reducing bounce and chain slap. And CAGE LOCK™ technology makes wheel removal and installation easier than ever. Paired with the X01 DH 7-speed shifter, X-HORIZON™ forms the backbone of X-ACTUATION™ technology—and that means completely smooth shifting action.

• X-HORIZON™ technology provides more responsive shifting and eliminates ghost shifting, a common problem on DH bikes
• X-ACTUATION™ with more cable pull delivers optimized system performance and durability
• Two cage lengths for various applications, including abnormally long chain stay growth
• EXACT ACTUATION™ (MTB 10-speed) variant allows upgrades to existing bikes in the aftermarket
• ROLLER BEARING CLUTCH™ with CAGE LOCK™ sets the industry standard
