Campy 10s fd shift issue
I have a chorus 2007 ct fd.
Centuar silver compact square taper crank 34 50 Matching centaur italien threaded bottom bracket Centaur silver rd What is happening is under load shifting to the little ring from big ring fails Seems to get stuck Requires a back pedal to get onto ring My guess is hanging up somewhere Any recommendations on how to adjust Thanks |

It could be any number of things without seeing it, but here is my best reccomendation to set up c10.
Remove FD cable Put adjuster barrel all the way in Put chain on largest cog and small ring Set FD limit so the chain is .5mm from FD cage Install FD cable by pulling cable tight Give the barrel a little turn so the cable is tight at rest Shift to big ring/little cog Make sure upper limit is set so the cage is just off the chain |

Picture?
Lower the front derailleur the better. I keep the outer cage sort of parallel to the chainring. The tail tends to get pulled inward and that really messes up the shifting. I use channel locks (on METAL CAGES ONLY) to tighten up the opening in the front. Just a mm or two, really makes a difference. Remember that the big->little is spring driven only, so any friction in the cable/housing will slow down the shift. Also, for same reason, any lack of lubrication in the pivots etc will also slow down the shift. I also adjust the derailleur to go past the small ring and I use a N-Gear Jumpstop (metal cage type guard) to keep the chain on target. Allows the "over shift" move without worrying about dropping the chain. Then click it a notch or so to center the derailleur. |

Thanks for the help
If I get a chance I will post pic Sounds like the lbs needs to check their work It shifts great except under load so I bet they wouldn't of caught it in a quick spin around block |

Remember, ONLY THE SPRING is moving the derailleur in the big-> small shift. If you put enough force on the chain I guarantee you your front derailleur will never shift to the small ring. With electric it's a different story. |
