"Used this on my old Bomber Z4 aria which normally use a 7.5wt but I decided to go down to a 5wt. I flipped the forks over to drain over night then put the the new oil in next day. Rebound is a bit quicker and the fork is a bit more fluid, damping is quieter as well."
"Great reliable fluid from a company with a vast knowledge of MTB fork and shock tuning. I've used this in various Marzocchi forks including the older open bath systems that like a nice quality fluid. Its makes a big difference compared to the factory used oil and can be mixed and tweaked."
