Hi Guys,
What could be working my front derailleur is not working.

it wont go on the Big rank or small crank, it is fixed on the middle crank.

cable looks ok and cleaned the front Derailleur.

from the handle side where the lever is I have not opened this as yet.

I did not do anything and this morning it was on the middle crank, as I usually leave it on the big crank.

Well, hard to say for sure from your description. If you push the lever and the derailleur doesn't move, then I'd replace the shifter unit. If it does move, then it just needs to be adjusted. Lot's of youtube vids showing how to do that, or just take it to your local friendly bike shop.

Well if the cable isn't broke and the front derailleur is still tightly attached to the cable your shifter is messed up.

Looks like you've got the old school xtr floppy shifter levers. They made those for 1 year only because a mountain bike isn't a road bike. They're special, let's say that.

Chances are a small piece inside the lever broke. If you love em you can find a replacement on eBay.

Or just to make sure you can try and lube the shifter. I know the old Shimano shifter pods could get sticky with age. Degreasing and lubing would usually bring an back. Yours look in great shape so probably a long shot. Another option could be to pull the cable from the housing, pull on the cable while you shift, if it moves in and out you might be ok.

Hi Guys,
Thank you for your replies.

I have attached further pictures, where I have taken pictures of the front shifter, the cable looks ok to me and the it was hooked on the metal tab near the shifter.

Once I take the tension of the cable from the front derailleur, you can move the lever, this may be due to no pressure, so you are saying the shifter is gone and the front derailleur is ok near the Crank area.

I rather if I can buy part, I can replace it, as this bike I only use it for commuting to work, I don't do any professional bike riding. Do you guys have the link to buy the part or replacement part of the shifter like for like.

Really appreciated for your replies for Canada and Usa.

either front shifter is broken, or cable is snapped in the middle, is there tension on the cable, and does it move when you push the shifter, or just stay put. I would say take the cable out, inspect it, check that it runs smooth through the housing, if thats all good, take your shifter apart and take a look inside, if that fine, check your derailleur, it may just be seized with rust or something.

Hi Traqs,
Thank you for your reply.
Cable moves but very slight , as you can see from the front derailleur and the cable looks stiff or has the tension, so the cable must be ok, as if it was snapped, then the cable would not slight move.

the shifter handle looks stiff, not going down, as it should and the cable does not move, as it is like something pulling the cable back, that how I feel.

I cleaned out the front Derailleur and no joy. I squirt wd40 and when I took screws out from the shifter applied WD40 and still the same , the shifter handle wont go down.

I will have to see if it easy to take of the shifter, as this has the gear and brake combined together.

I could not see Rust on the shifter or the derailleur.

Curious how easily the cable slides through the housing. Does it slide easily or is there a lot of friction?

Hi,
Just released the cable from the front Derailleur and the shifter handle moves freely, cable all looks one piece and the cable all looks greased as well.

could it be the front derailleur problem ?

Front derailleurs rarely go bad. If you can still move the derailluer by hand it's probably ok

Those shifters from what I've read are very sensitive to cable drag in the housing.

I would pull the cable out of the housing completely. With the cable out of the housing but connected to the shifter I would then pull on the cable and see if the shifter will pull in the cable and release as it should.

Hi
It was the front derailleur the culprit, after taking it out again and poking little screwdriver to clean again and after few push and it turn out the front derailleur was moving again and i connected the cable and it does work, but I will have to watch the video to set it correctly, as I can get it to small crank and middle crank, but cannot get it to the big crank. It is also slightly touching the front derailleur guide.,

So moved it about 10 times and it has released it. I will have to do it at weekend for the adjusting and setting front derailleur.

Congratulations!

Nice work Smile

Chances are if it's not going into be big ring you'll want to pull another 1-2mm of cable through the bolt & re tighten. Assuming you've got it mounted in the same spot and at the same angle as it was before.

Takes some time, but the more cable you pull through the farther out the derailleur will reach

Hi
I still can not get it to go on the 3rd crank, when I am doing it goes and then it does not go on the 3rd big crank.

It goes on to the middle and small crank.

I will have a another go at weekend, if weather permits, as I was doing on the floor without the bike stands, so make it a little bit harder.

I will watch some parktools videos.

you didn't check the range of motion of the derailleur? that'll be your problem
