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.

    Disk off center

    I was installing new pads on the new wheels I have mavic crossed. I have deore zr brakes. I noticed that the disc is not center in the opening. It doesn't hit but I'm assuming this is going to cause lopsided brake wear. How do fix this, does it need to be shimmed?

    Did the wheel get seated all the way in the dropouts? Pics might help the explanation.

    Well when it was fully seated that's when the disc wasn't centered. I offset it slightly without the wheel being cocked to much that it wasn't pointing straight and that fixed it. So what does that mean? Something else is wrong?

    I have noticed the disc position between brake pads can vary with how much I turned (or not) the QR nut.

    You should have the axle fully seated in the drop out.
    Some hubs are slightly different with their specs, one brand of hub might give you rub and another brand won't.
    I'd say your brake calipers need realigning.

    Does it very when the axle is completely seated or when you have offset it?

    There's play in the mounting holes on the caliper. Loosen the caliper only enough so you can move it side to side, apply the brake, and then tighten (while holding the brake on). If your pistons are both working and not sticking this should center the caliper on the rotor.
