Shimano front derailleur band compatability
Hi all, I'm replacing my ancient 105 groupset from 2007 with a 105 5800 groupset. I have a band installed on my seat tube already, but I was wondering if I needed to replace that as well. Can I just plug in the new 5800 front derailleur into the old clamp?

If this is the band used to mount a braze on derailleur without the braze on mount already on the frame? If so it's just a matter of bolting the new one on. If it's a band mounted derailleur your replacing, a band adaptor can be bought. Hope I explained that clear but sounds like your fine.

Front derailleurs come in two formats. Band-on and Braze-on. Band-on have a band which attaches to the frame. Braze-on do not, they attach to a braze-on on the frame or, as FeltF2Tarmac says, to a band adaptor.
You need to determine if your original derailleur is a band-on or a braze-on with band adaptor. If it is the later then you should be able to attach a new braze-on derailleur to it. If it is the former then you will almost certainly require a band adaptor (or you should have ordered a band-on derailleur in the correct size for your downtube diameter).
As usual, a photograph of the situation would assist greatly.
