Anyone knows if DA9100 brake/shift lever compatible with DA9000. I broke my DA9000 lever in a crash and want to upgrade to DA9100. Everything else on the bike is DA9000.

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.
