Can I adjust the pressure in my Reverb AXS seatpost?

Reverb AXS ships at 600psi in the 30.9mm and 31.6mm versions. The 34.9mm seatpost ships at 335psi. Most riders find that the shipped pressure provides the best balance of drop force, top-out rigidity, and ActiveRide compliance. The pressure range of the 30.9mm and 31.6mm seatpost is 400 - 600psi. The pressure range for the 34.9mm seatpost is 225 - 425psi. Riders will need a pump with a 600psi max pressure allowance to adjust the pressure in the post. Lowering the pressure causes the seatpost to have a lower drop force, allows ActiveRide to be more compliant, and has a softer feel at top-out.
