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.

    What determines 9x or 10x?

    Just curious if someone can please explain to me what determines if a bike can have a 9x or 10x rear cassette? I have a GT Marathon with a 135mm rear end....it being 135mm, does that mean it can't accept a 10x? OR is it the rear wheel/hub that determines? I have Crossmax SLR's with a 9x currently installed.....will it accept a 10x cassette? Any explanation for this newbie would be appreciated! Thanks, Blake

    you should be able to put either on your bike.

    it depends on what type of derailleur, chain, cassette, and shifter you put on it. if you want 10 speed, get 10 speed-specific parts. if you want 9 speed, get 9 speed stuff. 9 speed stuff is cheaper. having one extra gear is not necessarily going to get you anywhere faster, but the newest generation of 10 speed chains and derailleurs seem to be more reliable. SRAM type II and Shimano Shadow Plus derailleurs have a built-in clutch that virtually eliminates "chain slap" and prevents dropping the chain. the new 10 speed chains shift superbly as well. if you don't have the budget for blingy XT stuff, the SLX line is excellent as well.

    10 speed cassette on 9 speed hub?
