Choosing the right spring rate is key to getting the most out of a coil shock. Work out your total rider weight - including your normal riding kit - then use this chart to choose a spring. You can use the shock's preload adjuster to do the fine tuning later.
Please Note
These spring rates are calculated based on the Filter's kinematics. Even if you're used to running coil shocks on other bikes, you may need to check the right spring for the Filter. These calculations are based on 28% sag and a 65% rear / 35% front weight bias. On the Filter's 185mm shock length, 28% sag measures at 169.6mm eye-to-eye.
