ultegra 6800 FD for 10 speed?

is the ultegra 6800 front derailleur ok to use on 10 speed?

What shifter is on the bike? Shimano made more than 10 variations and I would not assume that they all are compatible. The amount of cable pull should be checked.

I've got the CX70 10-speed front derailleur in use with my 5800 11-speed brifters so I'd assume a 5800/6800 front derailleur would also work with 10-speed brifters.

The pull ratio of the 6800 FD is not the same as older 10 speed Shimano stuff, so I doubt it will work well. I have not tried it though I'll admit.

I'm actually kind of surprised that works.

Have to adjust it really precisely to avoid rubbing. Probably still not perfect with all gear combinations. A 5800 front mech would likely be better. Needed a top pull derailleur though and couldn't find one in the shimano 11spd series, don't know if one exist.

As far as I know, they don't exist. Not sure why. I have the CX70 on my cross bike too, but paired with a 5700 shifter, which it's officially compatible with. I'm more surprised it works because I thought the cable pull of the 6800 left shifter was less, so I'm surprised it pulls enough to actuate the CX70. Good news that it can be made to work!
