GForce shock synchroniser tool
GForce have introduced the shock synchroniser tool for the use with dampers of up to 122mm of length. Machined from high-quality aluminium the tool allows to precisely adjust parameters such as shock length, rebound or spring preload as it directly compares the behaviour of two shock absorbers during compression or expansion. Four thumb screws make for easy and convenient shock mounting while laser-etched metric and imperial scales display the exact measurements. The tool is available is black or blue anodising.
