I’m having the dickens of a time trying to install the rear derailleur cable. After installation on the cables, I have tightened up the tension in the reard derailleur wire, clamped it, etc., tightened the clamp screw, as per directions. I have tinkered with all of the screws, barrel screw, etc. The chain is not staying on the gear moving up the back cog or wheel. After releasing the right shift, the rear derailleur moves right back down to the smallest ring back there. The housing is perfectly cut and ended with correct cable stops. The barrel adjuster screw is all the way out counter clockwise in its tightest setting.
I think the problem is up at the right shifter. I threaded the cable through the winding wheel hole. I noticed that I still see the little knob poking out slightly to the right, just a tiny bit from the winding wheel hole. On the left derailleur, the little nob, however, was swallowed up by what looks like a protruding black plastic piece, and the left derailleur works perfectly fine.
Screw it, I think I’m just going to break down and take it to my LBS.
Here are below pictures of my right STI dura ace shifter. It’s pretty old, but it used to work. I think a piece dropped out. Not sure. The left one took the left der cable and nipple fine, and if you look at the left shifter, there’s a black plastic piece or holder for the nipple which swallowed the der nipple. On this one, it’s just a hole back out to the outer exit. I don’t have any more cable wire or a nipple to show you, but if you put it in, and threaded it through, the nipple will set into the whole. But its not swallowing or holding the shift:
Okay…I really can’t make out what you’re saying but this is what has to be done…as you know???
Okay, first of all buy new cables and cable covers (outers)…whenever I’ve had problems I have found new cables and cable covers have been the solution…especially the cables that fray at the ends if recycled and then it’s a bitch to thread through the cable outers…
Okay, click shift to the bottom gear (for example, if you have a 9-speed 12-25 cassette on the wheel click it 9 times to get to the 12 cogs) whilst holding the lever as if braking…this will expose the part where you need to introduce the cable into…as you know.
Now you will clearly see the hole out of which the cable will go out into the cable outer (cover)…thread it through and pull it out the other side until it sits flush and does not ‘poke out’ as you say…
Bottom line is it has to go in all the way and must not poke out…
Perhaps the problem is that you did not shift to the bottom gear when you put in the cable??? as I said above…
After you pull the cable out the other side only then thread it into the cable cover…and then stick the end into the opening…
What he said!!! Thats was my next suggestion. Start all over and be sure to shift all the way down to the small cog, before you put the cable in. Hopefully that will solve the problem.
BTW…I ALWAYS use new cables when I’ve pulled the others out for any reason. I never reuse a cable. Housings I’ll reuse but never cables. But, I’m also rethreading the cables into a Zipp frame. You CAN’T reuse a cable. It has to have the soldered end so it doesn’t ruin the internal cable housings with fraid ends. I also use shift cables, even for brake cables! The brake return is really sharp when you use a shift cable instead of a brake cable.
“…click shift to the bottom gear (for example, if you have a 9-speed 12-25 cassette on the wheel click it 9 times to get to the 12 cogs) whilst holding the lever as if braking…this will expose the part where you need to introduce the cable into…as you know…”.
That’s it. You are looking at it. I think this is the problem right here. I have clicked it nine times, and am bending back my brake exposing that hole. That’s what you see in the picture, when I put the der cable through that small black hole, the cable comes out the exit side, I thread it through the exit hole, until the small, der cable nipple reaches the nipple stop, in the shifter. (I think the problem is right here. I pull it until “what I think is set,” ) I then thread the cable through the cable stops and bottom bracket, all the way back and through the barrel adjuster. Eliminate any looseness in the wire. Tighten it. Clamp it, etc. It won’t hold any gear change and the derailleur drifts all the way back down to the smallest cog on the freewheel after shifting.
The problem is in the shifter. I either dropped a piece or the winding wheel isn’t working to keep the shift set up there in the shifter.
“The problem is in the shifter. I either dropped a piece or the winding wheel isn’t working to keep the shift set up there in the shifter.”
It must be the winding wheel…if it were th brakes then I would say you’ve obviously dropped the cylinder thingie with the hole…but there’s nothing else to drop that I can think of…are we talking Shimano here? I am…
