FREQUENTLY ASKED QUESTIONS ABOUT BICYCLE PUMPS
The best place to start is what type of valves your inner tube (or tyres, if you’re running tubulars) have. There are two basic types of valves that you’ll find on bikes: Presta and Schrader. For the most part, inner tubes and tubulars on road bikes will use Presta valves, and mountain bikes will use Schrader valves.
Balls take needle connectors, bikes take ones similar to car tires. If this is a hand pump, you will likely have to work hard to get enough pressure in the tire.
Yes, you can pump a car tire with a bike pump. I’ve done it before. However, you’ll have to be prepared to give a good 150 pumps at least for a tire that is only somewhat flat.
Proper tire pressure lets your bike roll quickly, ride smoothly, and avoid flats. Narrow tires need more air pressure than wide ones: Road tires typically require 80 to 130 psi (pounds per square inch); mountain tires, 25 to 35 psi; and hybrid tires, 40 to 70 psi.
You should pump up your road bike tires at least once or twice a week, or before every ride if you don’t go out that often. Road bike tires have been known to lose pressure after 4-5 days of sitting still.
You want a go-to pump that is easy to use, stable and strong, and has an accurate gauge. The typical road or tri bike tire should be checked for pressure and topped off with air before every single ride. A good floor bike pump will fill your tires quickly, even when they’re totally flat.
Regularly pump up your tires. A perfectly functioning tire will loose air over time. For starters, you should know that a normal, brand-new tire and tube will loose air over time.
The advantages of these pumps is that they weigh very little, fit easily in a bike bag or pocket, and they provide almost instant inflation to optimal pressure, which saves you the inconvenience of spending several minutes pumping.
