How do you add air?
Quick Question. Do you check your tire pressure in the morning before the ride at home? (I'm assuming so). Anyway, if your pressure is down a bit what do you do? Do you ride to the closest Service Station?
The reason I ask is because I've always ridden bicycles a lot I have a number of pumps in the garage so when my pressure is down a bit I just connect one of these. With a floor pump it is only a few strokes and you're back up. And, these only cost $20 or so for the cheaper ones at a bicycle shop. The better ones will run a bit more.
Furthermore, I carry a small bicycle pump with me in my saddle bags. I've used in the mornings a couple of times while on a trip to put in some air. However with these you need around 25+ pumps to get a pound of pressure. So while you "could" inflate a flat with it you'd get a good workout. But, it is light, doesn't rely on anything else and inexpensive. Again, if you check out a bicycle store you can find these guys, get the mountain bike kind as they are higher volumn and lower pressue (don't need to pump a Motorcycle Tire over 100PSI like a bicycle road tire).
