"8" spd derailleur with 9 spd cassette and chain
My wife just bought a 'cross bike with a relatively tall lowest gear
of 38x25 and 9spd Shimano 105 STI shifters and derailleurs. I'm thinking of swapping out the rear derailer for a mtb variety to accomodate a 32 or 34 tooth cog. I have a neglected old mtb with a STX derailleur from about 5 years ago that was probably designed at the time for 8 spd use. My wife also has a mtb bike purchased in 1999 with an LX derailleur that came with an 8 spd cassette. Any reason why either of these devices wouldn't serve the purpose? I would more than likely need a new 9 spd chain as there probably aren't enough links in the current one. Thanks for your advice, Victor PS In case you're wondering, I did in fact search through rec*tech for similar posts but didn't get that warm fuzzy feeling. I apologize for the unoriginality of the topic. |

I surfed around a little more and saw that Sheldon Brown had provided the same advice on his website. Unfortunately, and probably intentionally, the various derailers are marketed as being X-spd specific. Victor |

victor- Unfortunately, and probably
intentionally, the various derailers are marketed as being X-spd specific. BRBR yep, don't believe everything ya read or even hear. A local bike shop told a gent he would have to upgrade his entire 8s MTB drivetrain to 9s if he got the new 2003/4 XTR crank...baaaalllloney like that.
