front derailleur shim
I've got a Daytona triple front derailleur with a 31.8 mm clamp but my frame
has a 28.6 mm seat tube. Somebody a while back pointed me to www.bigwheel.com to buy a shim but I was just notified that they are currently out of stock. I'm located in Germany and haven't found any other source for a shim, nor for a Campy derailleur with the appropriate clamp. My next option seems to be to make a shim but I'm not real sure what the best way to go about it would be. What kind of material should I be looking for and in what thickness? Any suggestions would be appreciated, thanks. Rob Strickland |

You could also get one of these:
http://www.roseversand.de/rose_main....spr_id=1&mid=0 Sorry that link doesn't work, type 562083 in the searchbox and you'll be directed to the correct item. "Ronald" wrote in message ... You could also get one of these: http://www.roseversand.de/rose_main....spr_id=1&mid=0 It's a separate clamp (28.6) onto which you can mount any standard braze-on front derailleur. They're also available in other clamp diameters so when you switch frames you can get another clamp or just mount the braze-on derailleur when it's a braze-on frame. If you're not sure order their (Roseversand) catalog, it's free and has an image of the clamp in it. "Robert Strickland" wrote in message ...

That route would, however, require the purchase of another derailleur and I'd like to try to make use of the one I've got if possible. Thanks for the help though. Rob |

You can actually just buy the clamp part for the derailleur and get a 28.6 one. You need only remove a "C" clip and the clamp comes off. |

A long strip of mylar wrapped until the right diameter ( as with some seatposts) would probably work ,too. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |

front derailleur shim
Hi, Rob, you could cut a soda pop can into strips, with a pair of
scissors and wrap that around your downtube. You need to add about 1/8" (3.2mm) to the diameter, or 1/16" (1.6mm) of thickness.

front derailleur shim
robert- I've got a Daytona triple front derailleur with a 31.8 mm clamp but
my frame has a 28.6 mm seat tube. Somebody a while back pointed me to www.bigwheel.com to buy a shim but I was just notified that they are currently out of stock. I'm located in Germany and haven't found any other source for a shim, nor for a Campy derailleur with the appropriate clamp. BRBR Go to a LBS that 'qui si parla Campagnolo', or the equivalent in German and ask if they will swap the clamp...easy to do.

Paul- You can actually just buy the clamp part for the derailleur and get a
28.6 one. You need only remove a "C" clip and the clamp comes off. BRBR Yep but it is almost as expensive a front der... Poor idea for Campagnolo to stop making 28.6mm triple front ders, IMO- Peter Chisholm Vecchio's Bicicletteria 1833 Pearl St. Boulder, CO, 80302 (303)440-3535 http://www.vecchios.com "Ruote convenzionali costruite eccezionalmente bene" |
