X1 X-SYNC™ Chainrings

The X-SYNC™ narrow-wide chainring 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
  • CNC machined 7075, two-tone anodize
  • Mud-clearing recesses for the inner chain links and rollers
  • An integral component of the SRAM 1x™ drivetrain

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.

SRAM X1 Reviewed | Dirt Rag Magazine

“Whether you’re a cross-country, trail or all-mountain rider, this X1 group is a great way to get a taste of wide-ratio 1x philosophy.”

“The X1 group has fared great and despite the sometimes peanut-butter-like mud I’ve encountered, I haven’t noticed a distinct difference in performance between the two drives.” (XX1 vs. X1)

“The X1 group looks great and performs well. If you are looking to give 1x a try and don’t mind the extra grams, this drivetrain won’t let you down.”

SRAM X1 | long-term test | Enduro Mountainbike Magazine

“After 18 – parts very rainy – races and a lot of tours the drivetrain don’t show any signs of fatigue and still works as the first test ride.”

SRAM 1x11 drivetrain | long-term test | Enduro Magazine

The German Enduro Magazine published a long-term test about the SRAM 1x11 drivetrain. With each of these group sets having ticked off several thousand kilometers on their test fleet, they thought it was time to see how they were faring. The 1x11 drivetrains have been out on all terrains for serious testing - from the Bavarian mountains to the flowing trails around Stuttgart, and not forgetting the filthy wet lines of Scotland

SRAM X1 | Long term review | FeedTheHabbit.com

"During the course of my testing, shifting remained smooth with the ability to shift in a hurry or dump gears when encountering a steep incline unprepared. SRAM really has a corner on instant shifting. The competition is solid and predictable, but X1 shows just how fast shifting should be."
