FSA Pro Super Road Chainring

This chainring is designed for a 130mm Bolt Circle Diameter (BCD). Before purchasing, verify that your current crankset uses this specific 130mm standard, as it is not compatible with compact 110mm BCD cranksets.

AL7075/T6 is an aerospace-grade aluminum known for its high strength-to-weight ratio. Using this material allows the chainring to remain lightweight while resisting the wear and deformation typically caused by high-torque pedaling.

While it is engineered for road cycling, compatibility depends on your specific drivetrain setup, including the number of speeds (e.g., 9, 10, or 11-speed) and the chain width. Ensure your chain and derailleur system are compatible with standard road chainring specifications before installation.

Precision CNC machining allows for exact shaping of the teeth and shift ramps. This level of detail ensures the chain moves smoothly and reliably between rings, resulting in the crisp, consistent shifting performance you expect during a ride.

You can replace your current inner ring with this 39T option, provided your front derailleur has the capacity to adjust to the new size. If you are changing the tooth count significantly, you may need to reposition your front derailleur height to maintain optimal shifting.
