Allowed range: 50–65 mm
Enter the frame manufacturer’s published progression percentage (0–40%).
A provisional progression adjustment is applied to the baseline spring rate.
PROVISIONAL STARTING SPRING RATE
—
This is a preliminary spring rate estimate. It assumes a linear coil spring, minimal preload contribution, and negligible friction. Frame kinematics and rider position can change the correct spring rate recommendation. Confirm physical spring and shock compatibility, manufacturer limits, and sag before riding.
