1. The most important thing about buying a new bike is to make sure it fits. The only way you'll know if the bike is right for you is to size up the bike and make sure that the bike's geometry matches your body's geometry. Ask questions and do some research.

2. If possible, try to find a shop that will let you demo the bike on real dirt. Five minutes in a parking lot won't cut it. You wouldn't buy a car without a real world test drive, and a bike should be no different.
3. Don't belive the hype. Just because your favorite rider or best friend rides a certain bike, that doesn't mean that's the best one for you. Have an open mind and be realistic about your needs and ability.

    bearing vs. bushing

    This isn't really a question of which is better, it's more of what is the difference? Okay, you can quit laughing at me now, but I am quite mechanically stupid (city boy) and don't really know what the difference is between a bushing and a bearing. I have a Giant NRS and I think I read that it has bushings in the rear suspension. Any help or could someone refer me to a good site that explains this kind of junk to me? Thanks!

    Generally speaking, a bushing is a soft metal or plastic one piece part designed to keep a harder pin, shaft, or what have you, aligned while allowing free movement. The bushing wears out and is replaced as needed. A bearing is usually a three piece part consisting of an inner race, an outer race, and balls or rollers in between. Properly applied, bearings provide better alignment, less friction, and last longer.
    I'm not broke but you can see the cracks.

    I would have to disagree. Ever see a car suspension with ball bearings? Bushings are more approprate for high impact, low speed joints.

    Actually the reason they're used in cars is that they're cheaper to replace and fulfill the function just fine. Not to mention the fact that the bearings on bikes aren't subjected to the types forces the bushings on a car are subjected to.

    like a bottom bracket or headset?

    bushings are used on bikes because they're lighter and cheaper than bearings

    Bushings & needle bearings can handle loads especially laterall loads. Much more stability. A ball bearing allows flex with a laterall load like hard cornering.
