Valving Logic dyno tests of a kxf250 shim stack with an interactive crossover produces a crossover closure velocity of 25 in/sec. The PVP dyno data points show no evidence of crossover closure. However, the continuous damping force curve from Shim ReStackor calculations shows a subtle increase in slope at the crossover closure.

 

The Valving Logic dyno data includes separate measurements of the main piston, compression adjuster and the total combined damping force. The recorded data for each component of the shock closely tracks Shim ReStackor calculations for the configuration which also match the overall shock damping force.
