front derailleur shim

[Robert Strickla]

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.

You could also get one of these: http://www.roseversand.de/rose_main.cfm?cid=160&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.

Sorry that link doesn't work, type 562083 in the searchbox and you'll be directed to the
correct item.

Cut a strip of aluminum can and wrap as many times around seatube so that the 31.8 clamp is tight.

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.

Thanks Ronald. I'm aware of Roseversand and the clamp you mentioned. 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.

A section of a nylon or delrin tube is perfect. It need not be metal to work well. A long strip of
mylar wrapped until the right diameter ( as with some seatposts) would probably work ,too.

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.

Lewis.

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.

Yep but it is almost as expensive a front der...

Poor idea for Campagnolo to stop making 28.6mm triple front ders, IMO-
