Too much guad use - saddle too low or high?
I've noticed an overuse of my quads when riding on flat roads or the trainer/rollers. My saddle is pretty far back, enough that my knees are a good 1-2cm behind the pedal spindle. Could this be a saddle height problem?
Eventually I'll have time in my schedule for a fitting, but for now any thoughts would be appreciated.

Seat further back should elicit more hamstring/glute usage.....

Quads are for extending your lower leg. It seems to make sense that your saddle being so far back
is making your legs work pretty hard at the top of your pedal stroke when you are moving your foot forward. Try moving the saddle forward.

Get pics with your leg at the top of the pedal stroke, at 90 degrees forward, and at the bottom of the pedal stroke of your current setup

Knee area, but set back a bit so it shows you on the bike as well

Try lowering it a little. My seat was too high when I developed ITB, and it turned out it was from working my guads and not my gluts. I dropped the saddle a good 3-4cm (I was way too high) and my gluts started burning while the knee started healing.

The quadriceps femoris (quadriceps, quadriceps extensor, guads or quads) includes the four prevailing muscles on the front of the thigh. It is the great extensor muscle of the knee, forming a large fleshy mass which covers the front and sides of the femur.

Quads tend to be used more when you're not bent over, i.e. sitting more upright. This is related, I think, to walking.
Glutes/hamstrings are heavily recruited when you have an acute angle between your torso and your upper leg. Their main job is to help you walk/run uphill or keep you from toppling forward when carrying something heavy. On a bike they provide power when your body leans forward a lot. This is part of the reason why you automatically hunch over when climbing a steep/hard hill - your body tries to recruit those very powerful muscles.
Although moving the seat back helps make the torso/leg angle more acute, if you adjust yourself to sit upright, it doesn't help that much.
You can experiment by putting your hand on your glutes, upper hamstring, and quads, letting you feel when the muscle fires and how strongly it fires. Pedal a big gear on a trainer and vary how low you hold your torso. You'll find that a lower torso causes a much more powerful glute contraction.

I'd say move it forward and up. That may seem counterintuitive, but you're a pretty fast spinner. From personal experience, I was able to give my dominant quads a little bit of a break and work on hamstring strength by moving the saddle to KOPS and then up as high as I could while protecting the backs of my knees.
Have you ever felt the need to scoot forward on the saddle for hard efforts, especially climbing? (harder efforts seated, of course)
When I was riding flats exclusively for a while this summer, I raised the saddle even more to get a more balanced pedal stroke, because I wasn't dropping my heels as much on that terrain.

I did some longer (>1mi) climbs on Monday and was very comfortable in terms of saddle fore/aft. Didn't feel like my body wanted to scoot forward or backward. During my attack/break at Tradezone, I was chugging at about 140-150% FTP tucked down pretty low and my butt actually wanted to move back a little more.

Gotcha. Based on your last statement, I'd say raise it up first. If that feels like too much reach, then go forward a bit too.

extreme and early-onset cramping, plus excessive soreness (compared to the rest of my legs/body) the next day.
