the threads r teflon coated.. instead of bare Stainless like the SS

u need to be worried about salt on the piston.

rinse em or idk.. its like average temp 85 here all year

 

Isn't there a boot or something that protects the piston from these materials for the Flex?

 

Danny,

I think they should hold up reasonably well here in Alberta. Our winters get cold enough that salt is a waste of time, so they usually just use sand/gravel on our roads. I'd imagine with sand that as long as you're rinsing off your suspension often it should be fine.
