As the name implies, this compound is very lively and offers high rebound with lots of control and lean. For the same durometer, the APS will turn 10% to 15% more than the same durometer of other brands. In addition, the APS does not change much when you tighten the kingpin nut past snug. We recommend tightening to the point where it is difficult to turn the bushing in the bushing seat by hand. Use a flat washer for lower resistance and a cupped washer for higher resistance.
KranK™ Formula: Performance Under Pressure
Our highest rebound formula to date, KranK is designed specifically to change under pressure and is controlled by the amount of clamp pressure you subject it to when tightening the King Pin nut! The effective range of control is from barely snug for the loosest feel to 2 full turns for the tightest feel. KranK will turn the same or less than the same durometer of other brands which is also a departure from APS. As for washers, flat washers work great with this compound, but for the greatest control and range of this performance feature, use cupped, precision flat or precision cupped washers.
