A touch more info on triples, since you asked.
My triple, three chainrings on the pedals, are 48, 36, 26 tooth sprockets. These paired with a 9 cog (sprockets) rear cassette ranging from 11 to 32 teeth, let you go fast when you want to, and is still low enough to ride up a wall if you can get traction.
Another aside, bar ends, along with Ergon Grips, on a modified, means it has bends taking it up and back, straight/flat bar give you considerable comfort, and more places to put your hands.
Now, get out to some LBS today, and start riding bikes......
