A fox float 3 pos whatever the newish one is. Actually I snipped a 5mm spacer - left the 2.5 in. My RC comes with a 37.5 stock, and uses a 42.5 for 120mm. I know it works as the trail model is identical frame.
I have a deviate highlander for big mountain riding, so I just ride this for racing, marathon, and easier stuff.
Pedal strikes are mostly about technique honestly, but yeah - I run 165s (because mine is bad)
