About nine months ago I began eating healthy (off and on ), exercising and lifting weights now and then. I want to mix in more cardio into my workout, other than the same old treadmill workout. Basically, I don't know much about bikes (road bikes). I don't know of any good manufacturers, options/features to look for or how much a good bike runs. I do know that I originally wanted to spend $500, but am willing to move up to as much as $700. I don't usually put a pricetag on an item I want to buy and get whatever I can afford, but rather (like many of you, I'm sure) research it all I can and make an educated decision. I usually end up spending more than anticipated. However, not knowing what to look for, I didn't want to go hog wild on it. I live in Northeast PA and the roads are not great by any means. I'd likely use the bike for 85% cardio/workouts and 15% commuting (workout commuting ). Can anyone give me suggestions toward good names, good sites, good gear, etc etc etc? Also, I'd like to go to a local shop and ride some, but the closest is a Dick's Sporting Goods (an hour away. yes, I'm in the middle of almost no where) and they have mostly mountain bikes. Thanks for any help.
