The DVS gives recommended adjuster settings, too; but the rest of the information (spring rate/preload, oil height/viscosity) is already publicly. Also, with the double-adjustable air-assisted shock, the compression adjustment is based off the shim stack within the shock. 020" in thickness and. Dynamic Rebound: 14 clicks of shim-stack controlled rebound. Fork compression forces oil past these shims against the force of the spring - the amount of damping is determined by the number of the shims lifted off their seats by the oil pressure. Standard Shim Stack Configuration. Then, if they do your forks, they will ask you a bunch of questions (weight, riding style, terrain, opinions of forks), open your forks up, see what the stacks are in there, and put a revised stack in. 5mm, and supply shim material in larger sheets or coils. We do start to get into custom shim-stack tuning here, but shock technology and just manufacturing in general should allow for a product that is decently tunable externally and then easily modify-able should you need to go further (shim stack and weight/leverage charts). With the pinion bearing properly lubricated, increase or decrease the shim stack under the front bearing cone to achieve 20-25 inch/lbs of rotational drag or pre-load. Most places say about $175, and then proceed to nickel and dime you. This feature is similar to the concept of double-disc grinding springs for a flat surface. Selling a pair of fox 2.
