Product Information
Full details
This SRAM 30T chainring is designed for road cyclists seeking wider gear ranges and smoother transitions, particularly those using SRAM Force or Rival groupsets. Its primary benefit is enhanced climbing capability and efficient cadence maintenance. A potential consideration is its specific compatibility with 94 BCD bolt patterns and compatible SRAM groupsets.

FAQs
What does 30T mean for a chainring?
30T refers to the number of teeth on the chainring, which is 30. A smaller number of teeth generally results in an easier gear, beneficial for climbing.
What is 94 BCD?
BCD stands for Bolt Circle Diameter. 94mm is the diameter, measured in millimeters, of the circle on which the chainring mounting bolts are located. This is a specific standard that dictates compatibility with cranksets.
Will this chainring work with my Shimano crankset?
This chainring is designed specifically for SRAM Force and Rival groupsets with a 94 BCD. Compatibility with Shimano or other brands is not guaranteed and may require specific adapters or may not be possible.
What is X-Range gearing?
X-Range is SRAM's technology that provides a wider range of gears and smoother progression between them, allowing riders to maintain a comfortable cadence across a broader spectrum of terrain.
Do I need a new chain when installing this chainring?
It's recommended to use a chain compatible with your drivetrain (e.g., an 11-speed SRAM chain). If your current chain is significantly worn, replacing it along with the chainring and cassette will ensure optimal performance and longevity.
Can I mix this with other SRAM chainrings?
While possible, mixing chainrings can sometimes lead to suboptimal shifting performance. For best results, it's recommended to use chainrings that are part of a matched set or designed for the same intended purpose within your groupset.
Troubleshooting
Chain skipping under load
Verify chainring bolt torque. Ensure the chain and cassette are not excessively worn. Check for proper chainring alignment and potential frame flex.
Poor shifting performance
Re-index the rear derailleur. Ensure the chain is the correct length and the chainring is correctly installed. Check for any obstructions or damage to the derailleur or shifter.
Chain rubbing on front derailleur cage
Adjust the front derailleur limit screws and cable tension. Ensure the chainring is properly centered on the crank arm.

Setup, Compatibility & Care
Compatibility:
- Groupset: SRAM Force and Rival (check specific model year for full compatibility).
- Bolt Pattern: Requires a crankset with a 94mm BCD (Bolt Circle Diameter).
- Chain: Compatible with 11-speed chains used in SRAM Force and Rival groupsets.
Setup:
- Ensure your crankset has a 94 BCD and is compatible with SRAM Force or Rival chainrings.
- Remove the existing chainring bolts and the old chainring.
- Carefully align the new 30T chainring with the crank arm's mounting points.
- Install new chainring bolts (often included with the chainring or crankset) and tighten them sequentially and evenly to the manufacturer's recommended torque specification.
- Reinstall the chain, ensuring it is the correct length for the new gear combination.
- Perform a thorough gear indexing and adjustment to ensure smooth shifting.
Care:
- Clean the chainring regularly with a degreaser and brush to remove dirt and grime.
- Inspect for any signs of wear or damage, especially around the teeth.
- Lubricate the chain after cleaning to ensure smooth operation.
