Change Front derailleur Shimano M191 on Shimano FD-M590

[IstominIS]

Dear all.

 

I need your assistance. I'm new in MTB and have Trek X-Caliber 6 2014. The problem is my front derailleur Shimano M191. In some positions of front gear and back gear I hear friction in it. I've tried to adjust it but without success. I've decided to change it on Shimano FD-M590. The problem I see is that stock one designed for 8 ring cassette (which is installed) and Deore is for 10 ring cassette. Please, advice if it is going to work properly and if not, what change I can apply? Thank you.

I can offer a little bit of advice but I'm no expert. Firstly the best article I found on setting up a front derailiuer is here http://m.wikihow.com/Adjust-a-Front-Bicycle-Derailleur . Secondly I can tell you that I have a 9 speed fd installed on my 7 speed and it works fine. You do have to use your noggin though as the 2 smallest back rings do not play nice with the smallest front ring but this is normal.

 

Next a word of caution. I spent 2 evenings fiddling with the thing to get it right. It takes a bit of patience. Eventually you need to step away read some more stuff and come back to it. In some cases sleeping on the problem helps.

 

Now the last thing if you're trying to use a 10 speed fd on an 8 speed bike you may have a problem since as far as I know a 10 speed chain is much narrower than an 8 speed. This sort of compatibility thing is something I'm not that clued up about but a bit of googling will probably get you an answer.

Can you clarify in which 'positions'? Its normal to hear some friction when you are in the big blade on the front a the largest cog on the back. In that case you are 'cross chaining' and you are using your gears incorrectly.

Also, have you tired to adjust the limit screws? Google and do some reading regarding the limit screws..

FD are interesting little things.

 

You can adjust them up/down, clockwise/anticlockwise, limit screw top/bottom and tension tighter/looser. All these things can have an impact on "rubbing".

 

Theoretically you should be able to adjust your FD so it doesn't rub. Check out some youtube vids or the link above before you spend money.

 

Good luck!

Sorry for not replying for such a long time. I had a ACL reconstruction so I'm not riding at the moment. I have Altrus FD and this piece of crap doesn't want to adjust properly, adjustment bolt L doesn't make any difference. Looks like I'll have to buy something compatible with 8 gears at the back. Additionally to that I've broken my SRAM x4 shifter...

 

Thank you, guys for assistance.
