Hi Kk- Here's my opinion for what its worth- Some people love the cylinders, I am one of those who has had trouble with them so I stick to the old reliable bike pump.

However, I'm not strong enough either to get 87 lbs of air into my tires, so I bought a Topeak Road Morph bike pump. It fits on my frame, and when needed turns into a floor pump! It even has a gauge so I can at least get some idea of what pressure I have in my tire. Instead of pumping sideways, you pump like you would ordinarily- pushing downwards which gives you more strength.

The guys I ride with often use it when their pumps either don't work, or they get tired of pumping their way!

You can find these online for road bikes or mountain bikes if you want to see a picture.

One more two cents worth- always carry some kind of identification with you when you are out by yourself (an old driver's license with your address will suffice). A cell phone is also good.

Hope this helps!
