Durability Of Aftermarket Shifter Cables?
Can anyone comment on the durability of aftermarket shifter cables?
These would be for a Shimano 10S system. I have recently had one nearly break that was less than a year old and I think it was aftermarket. I can't recall having this problem with my other bike with 9S which used Shimano cables. The failure mode was broken strands near the shifter. It worked surprisingly good until a mechanic who was inspecting the bike for the upcoming MS-150 ride "adjusted" it. I had to readjust it on the way home. Later I decided to check the cable and sure enough found the broken strands. Should I only use Shimano cables in the future? Thanks, Steve |

Should I only use Shimano cables in the future? Shimano is not immune from bad cables: http://www.cpsc.gov/cpscpub/prerel/prhtml05/05102.html though this recall was for brake cables. I've used various brands of aftermarket, stainless steel (some Teflon coated, some not) shifter (and brake) cables and they've all been fine. Most of the problems I've had in this area have been with derailleur housing, not the cable within. |

It usually isn't the wire itself, rather the crunched plastic ferrule or some such. Check that and maybe replace the complete cable, not just the wire. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |

Thanks, Steve I replace my rear shift cable every 4 months and front every 6 months unless I notice broken strands earlier (800km/month, all weather commuting). If I let them go longer than that, they will break within a month or two. Maybe I just shift too much... |

How many miles in 1 year? If you ride a lot, replacing cables every year is a good idea. Indexed shifting cables do have a tendency to snap inside the shift lever, where you can't easily inspect it. |

Gee, that seems extreme. 1-3 years is more typical. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |

Never had a left cable fail. If I forget, the right fails by 3000. I've had the same experience with both 8 and 9 speed. Now I have a bike with 10 speed Force. Any input on the cable replacement interval for the right shifter? One footnote. Dripping energy drink makes a sticky mess under the bottom bracket that can have a real effect on shifting. I have wondered in the additional tension is a source of premature cable failure. Bill |

My experience with 9-speed Ultegra is that the shifter cables were fine for about 20,000 miles, at which point I replaced both of them; there was no visible wear or fraying on the old ones. But I clean and lube the cable paths about once a week, which might help extend their life. |

I changed out the cables on my 9 speed DuraAce bike this year just because they had 16,000 miles on them and I thought that was long enough. They still looked fine to me. And while I clean and lube the shifters and derailleurs when I feel the urge to have a clean bike, I don't do much of anything in particular for the cables. I haven't had a failure for a long time.

The outer casing and plastic ferrule was fine. I haven't had to replace an outer casing in a while (ever on this bike) in about 13K miles. Steve |
