1. What is SRAM AXS Chain Length?

The SRAM AXS chain length calculation method provides a simple formula to determine the correct chain length for SRAM's electronic AXS drivetrain systems. Proper chain length ensures optimal shifting performance and drivetrain longevity.

2. How Does the Calculator Work?

The calculator uses the SRAM AXS chain length formula:

Where:

• Largest Chainring — Number of teeth on the biggest front chainring
• Largest Cog — Number of teeth on the biggest rear cog
• 4 — The constant added for AXS systems

Explanation: This formula accounts for the necessary chain length to accommodate the largest gear combination while maintaining proper tension in all gears.

3. Importance of Proper Chain Length

Details: Correct chain length is crucial for smooth shifting, preventing chain slap, reducing wear on components, and maintaining optimal power transfer in all gear combinations.

4. Using the Calculator

Tips: Count the teeth on your largest chainring and largest rear cog. Enter these values to get the recommended chain length in links.

5. Frequently Asked Questions (FAQ)

Q1: Does this formula work for all SRAM AXS systems?
A: Yes, it applies to SRAM RED AXS, Force AXS, and Rival AXS road and gravel groupsets.

Q2: What if my calculated chain length is an odd number?
A: SRAM chains come in even numbers, so round up to the nearest even number if needed.

Q3: Does this work for 1x systems?
A: Yes, the formula works for both 1x and 2x AXS systems.

Q4: Should I add any extra links for full suspension bikes?
A: No, the formula accounts for normal suspension travel. Only adjust if using extreme suspension designs.

Q5: How do I count chain links?
A: Count each inner and outer plate pair as one link. The master link counts as one link.
