Front Derailleur compatibility

I’m trying make life a bit easier on my knees and am thinking about adding some more gears onto my bike using the odds and sods in the parts bin.

I’m currently using a set of 600 cranks with a narrow-wide chainring.
I’ve discovered an Ultegra 6700 fd. Does anyone know whether I could use the fd with the 600cranks (obviously once I’ve got the two chainrings on there as well)?

Thanks

No reason why it shouldn't work with a different model of cranks. The limiting factor is the difference in number of teeth between the small and large chainrings. Shimano docs says up to 16 teeth.

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

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
