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.

    How many bolts does my chainring have?

    I'm not sure whether its a chainring or crank, but its the pointy thing. I want to install a bash guard on my 2005 trek 3900, but I don't know how many bolts it has. How would I find out? From the look of it, it looks like it has 6 silver screw things, and 4 empty wholes. This is probably a crappy description, but I'm new to this. Can someone tell me how to find out?

    BTW I have a "SR 42/34/24" crank

    Thanks

    Find the thing with all the teeth on it that your chain wraps around. That's called a chainring and you have 3 of them. Now look where the biggest chainring attaches to your crank arm. The crank arm the thing with the pedal screwed on to the other end. The chainring should be attached to the crankarm with either 4 or 5 bolts. Count those.

    Ooooh. Good point. I just went to Trek's website and it does look like your chainrings are riveted to the crank. So you can't put a ring guard on there unless you upgraded to a different crankset.

    That's not such a bad deal though. Plenty of people (like everyone that I ride with) ride without a ring guard. Save that money and when/if you wear out or break the one that's on your bike you can by a stronger, lighter, better shifting crank. By then you may realize that you don't want a ring guard at all.

    Ya, from the look of it, there's 6 bolts. I may as well just upgrade the crank i guess.
