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.

    Shimano SM-RT81

    Hello,

    if anyone is using on his bike the shimano SM-RT81 rotors, i would like some suggestions and advice. I use the XT brakes with F01A resin pads and i was thinking about putting on these rotors (180/180) for better cooling and performance. Any thoughts ? I have seen the SM-RT86, too, which are a bit less expensive, but i cant understand their difference.

    Thx

    Which one you use depends on your wheel hub. If it is a Shimano centerlock hub, then use the RT81 rotors. If it's a standard 6-bolt disc hub, the RT86 is the one you need.
