What is the best back shock for a Banshee rider that will be racing MX and trail riding.

 

I had Works Performance rebuild my stock Banshee shock for about $350. It works very well. It all depends on how much you want to spend, how fast you want to go, and how high you want to fly.
Suspension is the secret to going fast. Get the best you can afford.
I would like to know the answer to your question myself. The magazines have yet to do a comparison on the aftermarket shocks and there is a lot of choices. Word of mouth is all we have to go on.
