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.

    Lower back pain?

    So why is my lower back hurting after about 30 min of riding. I just got into riding about a week ago and was fine until a day ago and now my other than my rear hurting my lower back is starting to be a real pain.

    You may be stretched out too much. You could try a shorter stem. You could also do some situps/crunches and other exercises to strengthen your back.

    When I started back up a year ago I had the same issue. A riser bar from the LBS solved my problem. Now my back only hurts when I wreck, which is to be expected.

    Keep your back pretty straight by supporting your torso weight with your core muscles, not you arms. Make cockpit adjustments (stem, handlebar, possibly saddle position) if necessary to accomplish this.

    As someone above mentioned, crunches, etc. could also help.

    My back hurts when I ride because of the length of my stem, it's too long.
    I have the reach too far forward to grasp the bars, causing pain in the lower back.
    Either get a shorter stem, or learn to ride with no hands so you aren't forced to lean forward so much.

    stem, bar, and saddle adjustment are critical....I was having problems with lower back pain about 20 minutes into a ride, it was so bad I couldn't ride more that a 100 yards with out having to stop and recover. I did some trailside work that involved swapping headset spacer around effectively raising my stem 1/4 of an inch....presto, back pain went away and I haven't had any problems since...

    Sorry for the noobiness of myself but wich would be the stem? Is it the part that extends from the handlebars to the front center post of the bike?

    I did order a carbon spacer from blue sky cycling in the 10 mm length. Will this help? I do feel like im too stretched out and leaning too far forward on the bike i was hoping this would help.

    you are right. it might be a good idea to order a few spacers of different heights so you can experiment with what feels best.

    That size seems a little big, even for your size, try a shorter stem.

    What do you mean by a shorter stem?

    And if i get a different bike should i go with a 21 or 20"??

    I mean im a pretty large guy it seems like the bike overall fits me right just it seems like im leaning too far forward.

    The stem is the part that connects the fork from the top of the head tube to the handlebars. Choose a shorter stem and possibly one with a greater angle which will make you feel like you are sitting more upright.

    I don't think 10mm will make much of a difference, but you never know. You can also try rotating your handlebars back a bit so that they're closer to you.

    You might want to get an adjustable stem to play with different set-ups:

    Im not totally convinced that the stem length is the right thing to change.... Swapping to a stem with more rise might be worth it in this situation though.

    If you're happy with the handling, a shorter stem will result in faster handling - and the way to slow that back down is with a wider bar (which will remove some of the point by pushing you further forward again).



    You could try an inline post (saddle further forward)...

    You could try a bar with more upsweep, or more backsweep.

    Good info. Also if the seat is tilted back too much or it's design causes discomfort to your nuts/crotch it can cause you to rotate your hips back to relieve the pressure caused by the seat, which can cause lower back pain too.
