Stark Varg Shock spring 42 N/mm

Shock spring rated at 42 N/mm, supplied singly for the Stark Varg's rear shock. Rate selection follows rider weight: a heavier rider needs a stiffer coil to hold ride height, and Stark can preset the bike's suspension to weight when it is ordered, so a change in rider or riding weight is what usually brings this spring onto the bench.
