Spring options available for changes in rider weight, riding style and/or bike. Springs are color coded based on spring rate (Orange = Larger riders, Black = Medium, Purple = Small, White = XSmall). Generally one spring rating up or down from your recommended spring is all you'd need. You can mix spring rates to optimize your setup and desired feel. 1.5" upper Spring, 1.75" lower spring.
Refer to the spring rate chart here to choose your spring. If you need help, give us a call.
