can anyone answer me plz....... :)

I personally have no idea, but you are going have to give way more details about what kind of bike, what you have, what you want, etc. No one will be able to answer with the limited info you have given.

It would help if we knew where you live. In any case, you have many choices but if you have index shifting, which I assume you do with 9 speeds, then it's important that you stay with the same brand as your shift levers. So check the levers and shop for 9 speed derailleurs within that brand, according to your budget.

my main concern is which derailleur should i buy long or short? i have founs some for 20-30 $ and some much more expansive my budget for both set (front and rear is 100-150$)
|
Again, the most important thing to consider is the brand, Shimano, Campagnolo, Sram, or other of the shift levers. That will determine which brand derailleurs you need. See if the levers have the brand written on them anywhere, and that's your starting place.

thats definitely shimano
|
OK, so we have a starting place. Next step is to look at the rear derailleur, and see if the frame has a built on hanger (extension the derailleur screws on to) or if the derailleur has to include the adapter. This is unlikely on a 9s bike, but you need to check.
Then you need to know if the front derailleur mounts to an adapter plate (braze-on) attached to the frame, or if the front derailleur has a band that wraps around the frame. All braze-on type are the same, but for a band mounted model you need to know the diameter of the frame. For long vs short cage, it depends on the gear range. The derailleur has a capacity expressed two ways. 1- the largest rear sprocket it can work with 2- chain take up capacity which is the issue in cage length. The capacity must be larger than the sum of the differences in sprockets, ie. for a 12-28 with 39-53 chainrings it would be 16+14 or 30 teeth capacity. So you have the FD type, and maybe band diameter, and a way to know which size cage you need, now it's about price for a pair of decent Shimano front derailleurs. |

We need way more information. Easiest thing would probably be to post detailed pictures of your components. Then we'll have a better idea what you're working with.

so levelers and derailleur should be same brand i guess :)
It's possible to mix brands, but complicated and shouldn't be done except by those who know exactly what they're doing. |

I have a few bikes, the newest of which is about 15 years old. I also own a titanium road frame given to me by the maker a few years ago, nut haven't built it yet because I told myself I'd build it when my current road bike dies.
|

You might want to visit the "Touring" forum to get information about long distance riding.

Or perhaps the hanger is bent, or the problem is related to the chain and/or cassette. Here's some information on problem solving: http://www.parktool.com/blog/repair-...illeur-systems |
