Yes - no problem.

Yes it is.

Here is the compatibility chart from Shimano. http://productinfo.shimano.com/#/com/2.0?types=road&cid=C-453&acid=C-455. It's quite confusing to read. Bottom line, everything is cross compatible between 9000 and 9100 EXCEPT if you have a 9000 FD, you need a 9000 chainset (as the spacing between rings on the 9100 is slightly different than 9000). The 9100 FD will work with the 9000 chainset but not vice versa.

In my experience chainset spacing is not that important. I'm on Dura Ace 9070 but I'm running Quarq Red chainset with 10-speed rings. Shifts are perfect. The FD limits are manually set and I can't see how chainset spacing could make any difference.

I agree that it seems like it should work ok. I wonder why Shimano says the 9000 FD isn't compatible with the 9100 chainset? Has someone here tried the two?

In any case, the OP asked about shifter compatibility, and the answer is yes (as the chart also shows).

The small chainring on FC-R9100 is 0.4mm farther inboard (toward the BB) when compared to FC-9000. The large chainring is in the same place respectively. Therefore the distance between the two chainrings has increased 0.4 mm from FC-9000 to FC-R9100. This allows a better chain line from the small ring to the smaller side of the cassette on frames with shorter chain stays.
The FD 9100 is optimized to shift for this spacing. I am convinced that the 0.04 is not enough to make the FD 9100 not compatible. There is photos of pro teams using FC 9100 with FD 9000's.

When using FD9070 on a FC9100 one could adjust the inner limit 0.4mm inboard and the problem is solved. I can't see how the FD9100 is optimized for the FC9100 unless the cage width has changed.

Theoretically the FD 9070 will push the chain 0.4mm short of optimum position over the big ring.

The range of motion is controlled by limit set screws, just like on a regular mechanical front derailleur.

I'm using the FD6870 with the R9100 compact cranks, zero issues.

Not sure this helps as I can't speak to mechanical, but the wife's bike ran fine with 9070 shifters and 9150 front and rear derailleurs.
Michael - The Anaerobic Threshold is neither...

There are definite quirks to adjusting the 9150 FD as opposed to 9070 (or any mechanical front derailleur). Instead of the typical low and high limit screw adjustments the 9150 FD only has a high limit adjustment and the low limit is set electronically - the same way Di2 adjustments are typically made. The big difference with 9150 specifically is that the range of motion is now determined by the high limit rather than the low limit. That is, the low limit is dependent on where you set the high limit screw. In a typical FD (mechanical and 9070), you set the low limit first, then set the high limit and that's your range of motion. According to the 9150 dealer manual, you set the 9150 high limit first and then electronically set the low limit.

I'm running a Cannondale SISL2 crankset on my Supersix Evo and had a tough time with my front shifting until I figured this out. With the high limit set with approx 1mm clearance with the big ring, the low limit adjustment was all the way outboard (no more electronic range adjustment) and it still had too much distance from the inner cage to the inner chainring. The net affect was my front shifts would not consistently shift from small to big ring while under any pedal pressure. Finally after reading the dealer manual and realizing I had to set the high limit first (which then defines the inner limit range) I now have to have my high limit set with slightly more clearance, about 2mm, which brings the inner limit closer to the inner ring and I now get consistent shifts. Unfortunately I have shifted the chain off the big ring once in a race so I'm leery of the exaggerated high limit adjustment.

TL;DR - the 9150 FD is a different from all other FDs that I've worked with. Compatibility with other cranks and chain lines takes some fiddling.
