Supreme sx 180mm. Seems to work well for DH and uplift. No need for a Dh race bike it seems. I have had a furious and canyon sender but keep going back to the SX. I take the dropper off for any bike bark stuff and just run a qr with a thompson post and ergon Dh saddle.
Don't you find single crown forks more unstable?
I have a dc bartlett 190mm which I planned to swap out for BP runs but honestly the 36 and push coil assembly have been great.. When the 29er 36 gets beat then will use the Bartlett to get my pesos worth.
My sx is stable with the 29er 36 and really cannot tell if it is that much different from a supreme dh with a boxxer coil. The back end takes most of the sting out of everything. Of course DC will be stiffer. My sender with a 40 elite had so much grip and got deflected off nothing. I just never feel like the 36 holds me back or unsafe etc. Most of my times are faster on the SX than any other of my 2016/17 Dh bikes I have owned and ridden.
I am not jumping huge but ride steep rough tracks. Faster on the SX, Also can climb on it if need be. It is not fun but i can say climb for an hour and not be too beat. Probably will not last as long as a full on Dh rig but I had that in mind when I got it.
