This is the stiffest of all available springs. These are only recommended if you’re a dedicated low-speed rider. Works best when most riding is through trails and hills. Adds a significant amount of tension to the belt. This spring reduces your top speed.

we recommend using no lighter then 12g rollers if using this spring.
