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.

    Help with Crankset/Bottom Bracket

    I have a Kona Fire Mountain with the original crankset and bottom braket (Shimano Deore). I want/need to change it out and need some help. I know I have the standard square design, but if I change the BB with the cranks, does that matter? I found a raceface set on eBay that looks to be a good deal.

    Any help or advice would be appreciated!

    That crankset should fit fine.

    I do have them. I was going to remove it myself, but have my LBS install it, just to make sure everything was up to snuff

    I don't see any reason for you not to be able to install it yourself too

    make sure you get a BB wrench if you don't have one.
    Honestly... ahh I give up

    installing an external bearing bb is easier than removing a square taper bb.

    like mtnbiker72 posted.....make sure 170's are what you want.

    standard MTB crank length is 175mm.....soooooo unless you are very short (my wife is 5'3" and pushes 175's) i would rethink this purchase....

    Does 0.2" really make a huge difference? I'm 6'3" so I should have 180s? I'm just looking at an easy replacement for cheap. My frame is 17" anyways, and I know that's way to small for me.

    I know...i know... I'm looking at Niner RIP9 in a large, but just don't have the $$$ right now. Hence the reason I'm cruising eBay for crankset deals lol. I'll try to find something with 175s.

    yeah, 6'3" on a 17" frame is awkward, unless for some freestyle/DJ type stuff
    shoot, monsters at 6'6" rock a 20" wheeled bicycle in the aerials.

    lol, I got a smokin deal (free) so I couldn't really complain. I upgraded to a 140mm Marzocchi fork so that made it less twitchy, and have an extra long seatpost, but I do look pretty goofy
