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.

    Upset Just got my New Goblin Need help with the drive train..... rear derailleur looks bent

    Like the title says I just got my bike in today and was so excited to set it up and ride however things in the drive train seemed pretty messed up. This is my first mountain bike so I'm pretty new to the game however I have watched about 8 videos on how to set up the rear derailleur and I still cant get it to work. I also looked in the Newbie sticky and tried his explanation. I would really like to get this fixed so I can ride to work tomorrow but at this point it doesnt look good. Please advise.

    It's normal for a new bike to need derailleur adjustments- limits, cable tension. etc., and a lot of times the derailleur hanger needs aligned as well. If your derailleur looks bent you definitely need to put a tool on the hanger and see what's what.

    I think I have figured out the L and the H screws but now my problem is that its jumping gears if i push the lever all the way down.

    It could be a bent chain or chain ring. You shouldn't of had to adjust the L and H screws.Derailleur adjustment can be tricky .Start with the chain in the smallest gear ,get the cable mostly tight ,try shifting ,if it doesn't shift ,tighten the cable until it does.

    Usually the derailleur isn't bent. The derailleur is attached to a hanger. Often this gets bent.
    It can be bent when you look down on it from above, left or right. It can also be twisted clockwise or counter clockwise.
    I have straightened a derailleur by eye by grabbing it at the top and bending the hanger derailleur assembly left or right. For a twist I have used a lockjaw pliers carefully to rotate it.
    A lbs can do it better by using a gauge, if you want to take it in.

    Although I still suspect that something is bent, I was able to get it up and running for its first offical ride this morning and all I can say is I am one happy man. It shifted pretty well, didn't give me a hard time at all but my legs hate me at this point. Thanks again for the responses I really do appreciate it.
