I would much rather have a built in gage / pump combo. There is not enough volume IMO in the tire to waste air getting the gage on and off. I give it the squeeze test and can tell if it’s low. But the recommendation to air each day or every other day is a good one. I have a cheap Bell pump that works really well up to about 80 PSI. Perfect for the touring bike. I like it because it’s small and light but still has a short 8 inch hose so I can pump against the ground. I always use it with an adapter and reverse the adapter and store it on the wheels as caps. The holder mounts to the rear rack and has storage for a patch kit and a spare adapter.The pop of air when I remove it is the air stored in the hose.
