Ive got a Stevens CX frame with postmount I haven't built yet, its the version previous to last year when they went flat mount...
Anyways, I was looking at the newly announced Ultegra group, but see the brakes are only listed as flat mount ..
My plan was to get the R785 Di2 shift/post mount setup before the new Ultegra was announed, but I sense this is about to become obsolete..
I have to admit, I know NOTHING about disc brakes so questions are....
1) If I get a set of 785 postmounts, are parts generally interchangeable... by that I mean are pads pretty well the same across the board and easy to get, not one offs specific to THAT model
2) Setting them up... there should be no reason why the new Ultegra shifters won't work with the 785 brake??
3) Are the disc brake units themselves pretty sturdy (ie, they aren't gonna self destruct in a season) what I'm getting at, if I can get a spare set, might be worth it??

I wouldn't bother with a spare set of calipers. These things are built to last!

BR-R785 - banjo connector (same as XTR, XT, SLX)
BR-RS785 - straight connector (same as Dura-Ace, Ultegra and Deore, Alivio, Acera)
for straight style caliper-hose connection: in future you may not found BR-RS785 caliper replacement and your best PM option will be Deore
(or you have to replace hose to use XTR/XT/SLX, it's hard to find mechanic who can change connector from straight to banjo on old hose)
