I'm in the process of moving my current groupset (Ultegra 6800) from my previous build onto a new frameset I'm building up. Whilst the band-on derailleur I have fits my previous frame perfectly, it's too big for the new build as it has a slimmer seat tube. Has anyone experienced this issue? I don't think Ultegra band on derailleurs come in different sizes..is there some kind of split shim I could install to make up for the excess space or something? Thanks in advance

Any advice on how to go about doing that?

Go to your LBS and see what's in their spares bin; Condor sorted me with a MTB shim that worked with a road FD for nada

You can buy shims, Shimano make them (seriously) and they're practically invisible when installed. I'm pretty sure I got mine from my friendly LBS, it's worth asking around as it's the sort of thing bike shops will have left over in their workshops.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot
