shimano 9 speed shifter with 8 speed cassette
My 8 speed dura ace sti shimano shifter is shot. Can I replace it with
a 9 speed sti shifter using my preexisting 8 speed dura ace derrailer and 8 speed cassette? Is there any intercompatabilty issues with 9 speed dura ace vs 105 vs ultegra? Thanks |

Is there any intercompatabilty issues with 9 speed dura ace vs 105 vs ultegra? Thanks A while ago I ran 9 speed sti shifters with 8 speed everything else for a few months (all of it including shifters were Ultegra). It mostly worked. I had an extra shift 3/4 in the upper gear range. I woundn't recomend racing it because it was kinda sloppy. It worked about 5 years ago, so propably will still. I'd get sick of it over the long term, but in a pinch I'd put up with it again. From what I remember, as long as you don't need an 11, your 8 speed hubs should be able to take a 9 speed cassette. You can then leave everything else alone. Did that with an old bike. Runs fine. OT Don't try running a 9 speed chain on an 8 speed cassette. That sucks. skippidy doodah. |

I just wouldn't want to for a really long time, esp when you can easily just change a cassette and be done with it. That is, unless you have a very strange rear hub. Some early DuraAce ones had strange hub bodies. A friend of mine couldn't replace his cassette at all because if it. He'd have to replace the hub body. shrug progress? |

Yes. 8x DuraAce shifters pull the same amount of cable as all 9x Shimano shifters do. Is there any intercompatabilty issues with 9 speed dura ace vs 105 vs ultegra? No, Shimano unified shifter cable pull/derailleur geometry as part of going 9x. -- MfG/Best regards helmut springer |

Thanks 8s DA rear ders are designed such that when using a 9s shifter and with a DA 8s rear der, it will indeed shift 8s spacing. |

Should you use a different Shimano rear derailleur, you'll shift 8 or 9 cogs on a 9sp cassette. The spacing on the various models of cassettes is the same for the same number of cogs. |

I've got one of those DA 8s Uniglide with a threaded on 12t cog. I'll be shopping for a new freehub body when these wear out. They made it exactly one year. Ron |
