I've been running a Z1 FR for 2 seasons, and it's never really felt right. It feels a bit too stiff and seems to ramp up too quickly. It's never had that plushness that I'm used to from Marzocchi forks. I originally had it on a Chameleon, so I actually sort of liked the extra stiffness. However, it's now on a full squish bike, and I feel like the front end is negatively affecting the performance of the bike as a whole.
I changed the oil and put the minimum recommended level in. That helped, but barely. I'm thinking the springs are too heavy for my weight (~160 lbs, geared up). I've had no luck finding any solid info on spring weights by color, so I thought I'd ask. They appear to be a dark silver color (almost titanium). One spring has a streak of red on the top of the coil, but I'm not sure if that's significant...my understanding was the springs were a solid color (all red/yellow/etc.).
