Developed for maximum chain control, each tooth’s thickness is precisely CNC-machined to support the chain’s inner and outer links perfectly.
Six available chainrings (28-30-32-34-36-38) allow you to tune your gear range to match your terrain, wheel size and riding style.
Each X-SYNC™ chain ring fits a single, universal spider—allowing you to change rings without removing the lightweight carbon crank arm.

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.

Ordered these cranks to shave some weight from my wife's bike. Shaved 200 grams! She is flying with these on her bike!
Excellent product at an excellent price. Crankset works flawlessly and is the lightest out there.
Light, super stiff and quite nice looking
