ok, i've decided that for safety's sake on the ULTIMATE RIDE, i'm going to buy the Airman portable tire pump that retails for $89 at BK. The box says it takes 8 mins to fill two tires to about 31psi. It's a mini air compressor so doesn't use cartridges or anything like that.
So, does anyone want to go in on a group purchase?'cause the more people, the cheaper.
