This leaves bottom out control to be a function of the air can. i dont see anything related to a circuit to control bottom out. its damping using nearly a port orifice until thats overcome then it switches to a shim stack until thats overcome, then it just blows open. this theory is inline with how the shock feels (blows through travel, poor midstroke). It looks like only a small amount of oil actually hits this upper compression shim stack, while the rest just bypasses the piston completely if the lower spring washer opens enough.
leaving propedal open bypasses the lower wave plate. From here it flows into the perforated foot bolt and into the center of the upper compression piston where it flows through an orifice and out a conventional shimstack.
Once compression forces the fluid to open up the first spring washer assembly, oil flows past it. These spring washers offer not quite a platform, but sort of a threshold for damping. It uses a large steel washer (not shim) to plug off the port, followed by concave spring washers to preload the rigid steel washer. The first piston blocks off the compression piston, but not in a typical fashion. It accomplishes this by a perforated foot bolt on the compression piston. Its sort of a two stage compression piston damper, but neither are floating pistons, just two static pistons.
I dont want to say sophisticated because i dont think it really works that well.
i dont want to get too optimistic yet, but i think i can figure out a way to turn an RP2(3) into something like an RPC, adjustable LSC compression! ill have time for pictures tomorrow. Hopefully this will serve as a guide for future users to service their own RP fox shocks at home, and tune them to their weight and style. i figured this was time to figure out whats happening in this shock, so i cracked it open. It ended up getting replaced by a much better shock, but this left me with a spare hanging around. I was never happy with the performance of my float RP2, or with the fact that i cant service or tune it.
