Mounting front derailleur to 1 1/8 seat tube?
I have a bike that needs a front derailleur with a 1 1/8 clamp. I want
to put a Campy triple front derailleur on this bike, only problem is that there's no 1 1/8 size clamp. I've seen adapter clamps that let you use a braze-on derailleur, or there are shims that let you use a 1 1/4 clamp on a 1 1/8 seat tube. Is there any advantage of using one over the other? Thanks, Ted |

Since it's getting hard to find the adapter clamps in 1-1/8 (your mileage may vary), I'd use the shims. They can be a bit tricky to position, but they work fine. Mark |

The shim allows you to screw up without a penalty. -- Typoes are a feature, not a bug. Some gardening required to reply via email. Words processed in a facility that contains nuts. |

Since it's not like you can add a braze-on to an aluminum frame easily, some form of clamp-derived method is pretty much required. -- Typoes are a feature, not a bug.

Not really but go see a shop that 'qui si parla Campagnolo' and see if they will swap the clamp assembly of a 31.8 for the 28.6 that comes on any Campagnolo double front der...But a 28.6 clamp assembly works fine. OBTW-Campagnolo will be amking 28.6 clamps only in 2006, along with clamps for 31.8, 34.9, ala shimano-a good thing, IMO Thanks, Ted |
