Fox Float Factory DPX2 2021. I tried to install this shock but the "backpack" didn't fit my frame as well as I wanted so I stuck with my original shock. If you're riding aggressively on the trails, then you're going to want suspension that can handle what you throw at it.The Fox DPX2 Factory shock is Fox's most advanced lightweight trail shock. It has a new base valve design and the addition of the valved circuit in open mode raises the already high bar for trail performance. The Factory version features a Genuine Kashima Coating that provides a slippery smooth feel that is ultra-durable.
