1. What is SRAM Transmission Chain Length?

The SRAM Transmission chain length calculation determines the optimal chain length for SRAM's dedicated transmission systems for motorcycles, ensuring proper shifting performance and drivetrain longevity.

2. How Does the Calculator Work?

The calculator uses the SRAM Transmission chain length formula:

Where:

• \( \text{Chainstay} \) — Distance between rear axle and bottom bracket (inches)
• \( \text{Chainring} \) — Number of teeth on front chainring
• \( \text{Cog} \) — Number of teeth on rear cog
• \( \text{Adjustment} \) — Additional links needed (usually 0-2)

Explanation: The formula accounts for both the chainstay length and the combined diameter of the chainring and cog to determine optimal chain length.

3. Importance of Correct Chain Length

Details: Proper chain length is critical for SRAM Transmission systems to maintain optimal shifting performance, reduce wear, and prevent damage to the drivetrain components.

4. Using the Calculator

Tips: Measure chainstay length accurately in inches, count teeth on both chainring and cog precisely, and add adjustment links if needed for fine-tuning.

5. Frequently Asked Questions (FAQ)

Q1: Why is chain length different for SRAM Transmission?
A: SRAM Transmission systems use a fixed derailleur position, requiring more precise chain length calculation than traditional systems.

Q2: How do I measure chainstay length?
A: Measure horizontally from the center of the bottom bracket to the center of the rear axle in inches.

Q3: What if my calculated length is between whole links?
A: Round up to the nearest whole link for SRAM Transmission systems.

Q4: Can I use this for non-SRAM drivetrains?
A: This formula is optimized for SRAM Transmission. Other systems may require different calculations.

Q5: What's the typical adjustment value?
A: Most setups use 0-2 additional links depending on specific frame and component combinations.
