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.

    MTB bar diameter???

    What's the diamter of a MTB bar? I was looking online at Nashbar and Performace and they don't state the bar diameter.

    Is it 25.4mm or 26mm? Can I use a road stem with a MTB bar?

    Most mountain bars are 25.4, some newer ones are 31.8; road bars are mostly 26, some 31.8s as well as a few other odd sizes. If the road stem is same diameter as the bar it would work, but may not be up to more abusive riding as a mountain stem and the rise/angle choices would be much different.

    Is there such a thing as a 28mm bar?

    What about 28mm? Is there a 28mm bar? Just wondering because I was looking at Nashabar and they have a pair of Profile Bar Ends that are made for a 28mm bar. Actually maybe, I'm not totally right on that one, but when you click on "More Info" from the link below, it says, "diameter----28mm". Is that a mistake?

    If it hasn't set in yet, thats the diameter of the bar end (not its clamp)

    Yeah, I realize that. However, on MTB bars all of the 25.4mm bars that I have seen have a constant diameter (25.4mm) whether that is in the middle (clamp area) or on the ends of the bar. In fact, I haven't been able to find a 28mm bar or even a bar that has 28mm ends.

    Sorry, if this post makes a lot of people roll their eyes, but I'm new to this. So, if anyone can the error in my reasoning or maybe tell me where to find a MTB bar that has a 28mm diameter, I would greatly appreciate it.

    Actually, this is what I was hinting at:

    Typicly, MTB bars are 25.4mm (1") at the center where they are clamped and 22.2mm (7/8") where the controls and grips mount.

    Road handlebars are usually 26.0mm or 26.4mm at the clamp.

    Usually, road and MTB stems are not interchangeable -- but there are exceptions.

    There are several oversized bars on the market for both road and MTB -- 31.8mm (1 1/4") is becoming more common.

    I've never heard of any handlebars with a 28mm diameter anywhere along its length.
