Will it be ok to use an portable air tank with only 10 lbs of air on these shocks?
Have low pressure air gauge 1-25 lbs (used for athletic equipment).
Thanks

 

Plenty of members use touring bike air shocks without a tank. The factory don't use a tank on the touring models and I can't see any benefit of using one on a Sporty.

 

I don't know how much air you plan on running but I'm only at 0psi when solo and 4/5 psi when 2 up, maybe a couple pounds when I strap a bag to the back. I just use a hand pump like this It adds about 1psi per pump so it isn't hard.
