Help needed!!! What kind of group is this? ~20yr Bianchi bike, Campa group.
I bought this beautiful oldtimer bianchi road bike about a year ago.
It has written the name Record 920 on the frame. I liked it so much, I took it from Germany to the US when I went there to write my thesis. On the way back Delta damaged the gear group in the back. Before I can start looking for the replacement part I'd need to know what type/year the campagnolo group is. Pictures are posted he http://www.physik.tu-berlin.de/~mxhf...WWW/index.html I guess it is about 20 years old. There are no catalogs online for such old parts. Does anybody know, or know where to start looking, or know where to get parts even? I tried shops, I tried Bianchi, I tried ebay.... i think I tried the obvious things. Max |

V and T pedals though were triangular platforms so those are different - brake levers look different too but maybe someone just changed the hoods. Triomphe levers had "Campagnolo" in kind of a script engraved on them, not sure about Victory. Mine's now my keychain. Short-lived entry-level gruppi, 1984-1986 or so. Maybe check campyonly.com for more photos. |

Also, I could be mistaken, but the chain appears too long. If it is too long, it will shift better when shortened to the correct length. My $0.02, Good luck, John I don't think the chain is too long. from some of the pictures, it would be just as possible to say the chain is too short. Also, not the case. Obviously something changed, during shipping. Whether the derailleur itself is damaged or the hanger, or just an adjustment, hard to tell. For the OP, have you taken it to a shop and asked them? It may be something simple. Life is Good! Jeff |

This pictu http://www.physik.tu-berlin.de/~mxhf...s/img_4729.jpg shows an intact stop on the derailleur hanger, so a replacement is in order. IIRC, this was a weak point of these derailleurs. I could be worng, though- those are 17-year-old memories, and I ain't getting any younger. Jeff |

Is your purpose to totally restore it to new condition? If not, you can use a newer & probably superior derailleur for less money. I agree in principle, but a modern derailleur might have to be modified slightly to work with his wide chain. It looks like he's got a 7-speed system. Also, if his shifters are friction rather than indexed, his choice of derailleur would be greater (Shimano, Sun Tour, etc. as well as Campy). Art Harris |

Wow,
thanks you all you guys!!! Ok the pedals are actually shimano (brrrr, I know) and quit new. Yes there is this little ring around the screw which fixes the hangar to the frame. The ring is about 7mm wide. It had this thing sticking out at one side which held the hanger in place. The ring had little teeth at one side and could be positioned in three different positions for different chain lengths. It is the only thing which is broken. It very small, very simple....but still difficult to get. I will now dig through the catalogs you sent me. Thanks again!

Hi Jeff,
thank you! I assume the cast stop is this little ring with the thing sticking out which pushes against the little knob shown in that picture? The "thing" broke off that ring. Any idea where I could get a cast stop?
