(190 × 2.46²) ÷ (2.56 × 0.30) = (190 × 6.05) ÷ (0.768) = 1149.5 ÷ 0.768 ≈ 1497 lbs/in → That’s huge — obviously wrong?

Or in metric (kg/mm – less common for Fox): [ \textRate (kg/mm) = \frac\textRider weight (kg) \times \textLR^2\textShock stroke (mm) \times \textSag ] (accounts for preload & bike’s falling/rising rate): Use an online leverage ratio curve or average LR at sag point. Many use: Rate = (Rider weight × LR at sag) ÷ (Shock stroke × Sag) 3. Step‑by‑Step Example Bike: 160mm rear travel, shock stroke = 65mm Leverage ratio = 160 ÷ 65 ≈ 2.46 (average) Rider weight = 190 lbs (86 kg) with gear Desired sag = 30% (0.30) Shock stroke in inches = 65 ÷ 25.4 ≈ 2.56 in (190 × 2
