Got tire valve adapter last night, pumped the tires not to have too much sag (dont have/probably dont need a pressure checker since it boils down to my weight being carried, right?) and now it all feels right. Probably gonna go get a lock set, rear rack, spare tube, etc today.
Nooo! With road tires, you have to pump them up to the max or near it, or you'll get pinch flats, wherein a rock hits the wheel and pinches the tube (visible on the tube as two holes, which is why it's sometimes called a snake bite). I regularly pump our 700 cm tires to 120 PSI. Check your sidewalls for max inflation. Also, you may want to slap in new tubes anyway if the bike hasn't been used in a while. The rubber wears out, and tubes are cheap.
A good pump isn't super expensive any more and they have gauges on them, along with a universal chuck that will fit both Presta and Schrader valves. (I have a Giant brand pump but I'm sure other brands have similar features.)
Bicycles, like cameras (and any other hobby), have a Gear Acquisition Syndrome.
