SPRiT  MX  Multi-Stage Springs      
 
-  Prototyped in Sep 2019,   Announced on 18 Mar 2021 
-  Challenging to 99.5% Supreme Precision - avrg 0.3g variance  
-  Made in Korea of super-precision premium materials under SPRiT control
 
I have designed these Multi-Stage springs to be curved as in the graphes.
The Multi-Stage springs have been sampled along with Progressive and Complex springs since 2016, fixed some issues in 2019 and released in a broad spectrum in 2021. 
 
* No Polarity on Multi-Stage springs 
  According to the Newtonians,   Fab  =  - Fba  
 
  You can say this simply,  "When you press the lighter end, the heavier end will be pressed by exactly the same pressure. vise versa."    or  
   "It damn doesn't matter, which end.  You feel the pressure exactly by the pressure you press."
 
Please Enjoy Your Premier Builds
