SPRiT  MX  Progressive Springs      -    World Premier since Oct  2018

 

'P' Series  New v1.2    Jan 4, 2019    -    More Progressive ! 

    

 

I have designed  v1.2  Progressive rate springs to be much lighter than normal springs by 6g - 10g until actuation point as Graph 1.   The force rises rapidly after actuation point, results in the same bottom out weight as conventional linear springs.  

If you feel like to experience bouncier bottom out with a certain actuation force, please try one or two level heavier bottom out springs as Graph 2.  

Progressive springs are hard to find any practical examples in the electronics, the production is utterly trickier and takes much longer time.

  

Please Enjoy Your World Premier Build,
