good info! Its good to know the recommended settings are likely not far off from "ideal", especially for an average rider. Also interesting that a bit more PSI resulted in a better ride - I found the same in my limited experience to date with the Float X2.
I've also observed the difference in pressure when checking. I suspect it may be a combination of temperature and elevation changes, any small internal pressure changes with heat while in use, maybe lose a bit putting the pump on/off. As said above, I doubt the pressure change is solely due to the small ambient temp range we're talking about.
A similar article on the rear shock would be great. and what sort of digital pressure gauge do you use?
