260 is not crazy high, most bike shocks max out at 300-350. It's all about surface area of the piston: a Float X has piston area about 2 and a half square inches, so 200 psi gives a starting spring rate of around 500 lbs (super simplified, ignores negative spring, but you get the idea hopefully that the pressures aren't insane. And the second chamber is extra high to start because it is designed to only move later in the stroke, when the main chamber has increased in pressure, effectively growing the volume of the air chamber to keep the spring rate closer to linear.
