    i don`t have another problems while riding the bike, it`s the only problem but it`s very painful one.
    i don`t ride a professional bike but it`s pretty comfortable to me, the main thing that i don`t know is how to fit the bite to myself.
    please help me .

    "fit" is a big general question and hard for soemone to answer that doesn't know you or the bike. also considering what section this post is in there may be other issues to take into account when "fitting" the bike to you. initially I was thinking of suggesting something about your posture while you are riding. I read something a while back that helped me be more comfortable, and that was the sensation of your posture on a road bike should be you should feel like you are sticking your butt out with your back arched. of course you won't look like that, even only pro racers have straight backs, but that's the effort to make on a road bike, instead of arching forward like you are picking up a bushel of apples. "hunching" over is not the right posture.

    I have a 2 level PLIF at L4-L5 and L5-S1 from a spinal compression. The position described above, as close as I can come, with the straight back using drop bars is the most comfortable and pain free position for me. The bike fit put me in the correct position with stem length and bar height in relation to the seat. the link fro 10-Wheels has what you need to fit the bike to you properly but the exact placement of the seat in fore/aft placement, its height overall and in relation to the top of your bars will be up to your physical abilities in terms of flexibility. As my back got used to riding on the bar tops and lever hoods I found I could take out about 15mm in stem spacers since I could bend further without pain. If I try to ride with the back hunched up, any at all, I get severe pain in the surgical site. Keeping my back as straight as possible relieves my back issues.

    What type of bike (hybrid with straight bars, road with drop bars, mustache bars or others? Do you have any disk injuries or degenerative disease in the disk or vertebra? Even the crank length and pedaling can effect your back pain. If you want a book that you can get valuable fit information and how to from try Lennard Zinn's "Cycling Primer", http://www.amazon.com/Zinns-Cycling-...s=Lennard+Zinn he has a great opening section on how to fit your self to suit your body's dimensions and quirks.

    Sorry for the length and I hope you can get things sorted out, maybe a good LBS can help you out with a fitting session. they will probably charge you unless you ar ebuying a new bike but it would be worth the cost.
