    Rear Derailleur Cable broken off inside Ultegra STI shifter

    I have a Commotion tandem. Recently my rear derailleur cable snapped off inside the Ultegra STI shifter leaving frayed cabling forever jammed inside the shifter housing. What to do?

    If the remains are just inside the cable housing, just replace the housing and cable. If the remains are all down inside the shifing mechinism, see if you can remove the bit after shifting out the shifter (small cog position) and try to push it out the way it was installed.
    Bikes use brakes to stop.

    If your bike has breaks, don't ride it.

    If I read you correctly, what's left in the STI shifter is the cable anchor and some tiny amount of frayed cable. Get the shifter to the high gear position by pushing repeatedly on the small lever until it stops clicking. Now pull on the brake (to expose the shifter innards) and you should see the cable anchor head exposed on the right side of the brifter. While holding the brake lever, go into the left side of the brifter with a paper clip (or something a little narrower than the derailleur cable) and try to poke in the hole where the cable would normally exit the brifter. This should cause the cable anchor head to pop out on the right side. If you can just get it to come out a little bit you should be able to grab it with some needle nose pliers and yank it out the rest of the way. The important bit is to get the control shifted to the point where you'd normally install a new cable. Assuming you can get it out as I have described, you will be all set to install a new cable. Unless there is something damaged in your shifter, this should be very easy to do. Good luck!
