I've got an Attack 20, 1.7" X 129 with a 3.0 pitch and am looking for set up tips for out west powder riding. I will be using my stock 1" for the flatlands. Just wondering if anybody is using this set up. I believe I need to run the 8" extrovert drivers, but am wondering which clutching and gearing to use? :beerchug: :fluffy: Thanks!!
