There is a bolt on the derailleur that holds the cable. Loosen it to remove the cable from the derailleur. If there is a cap on the cable, remove it by pinching it with a pair of pliers. i do not know what style shifters you are using, but most all of them have a plastic cap covering the port for the cable. Shift to the highest gear to prep the cable for release and remove the cap. Push the cable back into the shifter and it should come out of the port you opened. Now, slide the new cable in and pull it through its circuit of cable housings and back to the derailleur. Attach the cable and shift to the lowest gear (big cog). Now, pull the cable along the top tube or seat stay (wherever it is more accessible) away from that tube very firmly several times. This pre-stretches the cable and minimizes necessity of adjustment later. The harder you pull, the better. Once you have stretched the cable, shift to the highest gear again and release the cable on the derailleur. Adjust the barrel on the derailleur to the center of its range and turn in the one on your shifter all the way. Now, pull the cable taut and reatach it on the derailleur. You can cut the cable to length and put a cap on it now. Shift into your middle gear and use the barrel adjuster on the derailleur to align the jockey wheel over the appropriate cog of the cassette. You should be all set!

i hope this helps

I have an electric RMartin R10H, and replaced the 9c motor hub. But, the derailed is no longer aligned. Cog needs to be moved outward by 3/8 inch or so. Is such an extender available?

Are adjustment screws all the way out? If so, frame won't accommodate this cog. ITs too wide. Sometimes a frame spreader will correct. This repair is difficult to do, contact local bike shop for assistance

Shimano alivio front derailleur doesn't shift from intermidiate chain ring to the smallest chain ring in a inclined riding

There is typically not a single cause or solution to a specific shifting problem. The most common way to resolve your problem is to let off a bit on pedal pressure as you shift. The derailleur has to move the chain sideways off the teeth, and that is more difficult when the chain is under high pressure.

I want to replace the derailleur what should i get

Any Shimano rear derailleur that is specific to the amount of cogs you have in the rear will work. Alivio is the entry into the nicer derailleurs. The more money you spend, the nicer they get: lighter, more machining, a more precise fit of parts.

If there is no internal routing under the covers, check the sides near the triggers. There will be a black plactic phillipes head screw. Shift the derailleur down the high gear or where all the tension is released from the line. Disconnect the cable and feed it backwards towards the shifter. the cable will come out the hole where the cable previously was inserted

My Shimano Alvio 3-speed front shifter has

rough guess, from past life of bmx.
there should be a cable that runs down to the mechanism, the cable is secured by a small nut, loosen the nut and pull the cable a little more out of the nut with pliers. tighten the nut, and try the linkage.
the shift cable stretches over time and your actually gonna make a small adjustment to compensate for the stretch. by just pulling the cable thru the locking nut to make it shorter.

Shimano 105 10 speed rear derailleur doesn't shift up or down well and doesn't stay in gear. Fairly new ( 250 miles)

Try this:
Set your shifter to the highest gear while turning the crank. If you have to, manually set the derailleur to the highest gear.
Release the derailleur cable by loosening its screw.
Pull the cable taut and re-tighten the screw that clamps the derailleur cable.
You should be all set.
The cable stretches over time. This can be avoided by "pre-stretching" new cables. To do this, simply shift into first gear and pull the derailleur cable away from the frame (where you are able to do so) fairly hard, several times. Then you just release and re-tighten the cable like mentioned in the steps above.
Happy riding!

I am having problems with my Shimano front derailleur

Adverse temperatures can affect metal, and left idle over time the cables can stretch.. It needs adjustment. Usually the is a pair of screws on top which limit the movement of the derailleur.
