App Description

SpringRate converts between spring rate, wheel rate and ride frequency so you can dial in a suspension setup with real numbers.

Enter spring rate, motion ratio, spring angle and sprung mass to get wheel rate and ride frequency — or solve it backwards from a target frequency to the spring rate you need. Compare front and rear to set your ride-frequency spread.

FEATURES
• Wheel rate = spring rate x motion ratio squared x cos(angle)
• Ride frequency from wheel rate and sprung mass
• Reverse solve: target frequency to required spring rate
• Front/rear frequency spread (flat-ride)
• Metric (N/mm, kg) or imperial (lbf/in, lb)
• Save your setups
