Broken rear derailleur cable - DIY replacement.

 



Last week my rear gear cable broke on the way to the annual picnic. This is the broken end of the Shimano Ultegra shifter cable - jammed in the cable groove of the ratchet within the shifter assembly. The problem is cycle repair manuals don't explain how to deal with this - they focus on the easy bit of replacing an old cable / fitting a new one. The solution? - a search on YouTube: there is always an answer to the most intractable problem. https://www.youtube.com/watch?v=MWDuQRXiGO4&t=697s

Once on the bike stand it was reasonably straightforward to follow this video, iPad on the workbench, pausing the clip now-and-again to follow each stage of the repair. To avoid this happening again, I'll follow Dave Vine's advice and replace the rear shifter cable annually as a matter of routine maintenance!

Even my Haynes book 5th edition is not a lot of help! Other than you must put in top gear position before replacing anything. Looking at the picture the cause may be a rough edge to the outer cable ?.?
