X1-1200 X-SYNC™ Crankset
1x PERFORMANCE AND DURABILITY
Quality and durability combine in the SRAM X1 crankset to deliver consistent performance every time out. Featuring SRAM’s X-SYNC™ tooth profile, the X1 crankset is engineered for complete chain control. Each tooth’s thickness is CNC machined to work seamlessly with the chain’s inner and outer links. And with five available chainrings, you can personalize your gear range to match the way you ride.
- CNC machined 7075, two-tone anodized X-SYNC™ chainring—an integral component of the SRAM 1x™ drivetrain
- X-SYNC™ tall, square tooth design provides maximum chain control
- Sharp, narrow tooth profile and rounded chamfer edges help manage a deflected chain
- Mud-clearing recesses for the inner chain links and rollers
- 7000 series forged aluminum arms

Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.
GXP’s Gutter Seal design cuts friction and weight—improving both feel and performance.
A variant of the external GXP bottom bracket, PressFit cuts weight by up to 40 grams and eases installation by allowing you to press the bearing cups into the frame instead of threading them. It requires no change to the crank spindle length and diameter.
- Pressfit 30™
This is a new design led by SRAM. It’s all the best from BB30 and Press-Fit bottom brackets in one captivating package. This bottom bracket is designed for 30mm spindle cranksets. The key difference with PressFit 30 is how the bearings are fitted into the frame. Bearings are housed in nylon cups which will be pressed into the frames bottom bracket shell. PressFit 30 will feature an integrated seal, pre-assembled into the cups, to further prolong bearing life. Frames will need a 46mm inner-diameter bottom bracket shell to accommodate this system. PressFit 30 for road will require a 68mm wide shell while PressFit 30 for MTB will require a 73mm wide shell. Advantages: Huge weight savings, narrow Q-factor, more ankle clearance, greater bearing durability, stiffer/stronger crank construction, simple installation. Allows for larger diameter frame tubes increasing frame stiffness. Drawbacks: Still searching.
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.

“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.”
“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.”
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
"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."
