My new 08 UC came with about 5 psi in the rear. I fired up the compressor and dialed down the pressure to 30 and put 20-25 psi in my rear for my mostly solo riding. I noticed on my first ride with Mrs O'Lady that we were bottoming out. My gauge lets a couple psi out when I measure which is why I don't know the exact psi.
 \\;I wish I had seen that a week ago, I bought one from the stealer,$43+tax,, \\; the relief button dosent seem to work either \\; is there any trick to it? \\; I may just have to return it
I set the pressure \\;this spring &\\; \\;checked it once or twice since but no need for adjustment. \\;
 \\;
Is it necessary - for most - to \\;add air \\;frequently?
I never understood why anything more than a \\;bicycle pump is needed. \\; I can't imagine using the pump more than twice a year. \\; Am I missing something?
