Don't rely on the gauge to much, you can be at 100 and be bottom out and be at 100 and be perfect. I noticed after a while when I let all the air out the gauge is at about 10 or 15 so I don't think those gauges are to good, I'm about to pull mine out and eliminate one possible air leak
I usually ride at 100 alone, 120 with my skinny son and about 150 with my wife.
I just adjusted until me feet are comfortable flat on the ground and not bottoming.
Why you guys need straps?
I have been running with this system for a while and I have never touched the pipes, if the shocks are raised to much and are close to the pipes the bike will look awfully bad, way to high and my legs will be way off the ground.
But wait! Maybe because I'm short, 5'06, I don't need to raise to much and guys with longer legs need to go higher therefor shock is closer to pipe, sometimes been short has advantages.
I love my system, for those guys still thinking about, go for it, you will like it.
When I have to push back with my legs I lower all the way down, it's much easier and I have more control of the bike.
