Would this work?

Hey everyone. Been riding road for years now, but this past year, I purchased an Open UP and have been riding 65% off road now and 35% road. Loving it!!

Anyways, it's that time now....thinking about making some changes to my gravel bike.

Current drivetrain set up:
- Sram Force 1 x hydraulics
- Easton EC90 SL direct mount Chainring (38) with Easton EC90SL cinco cranks
- Post mount Sram disc brakes
- Sram 10-42 XO cassette
- Industry Nine hubs with Sram XD driver hub body

This is what I would like to do:

- Ultegra di2 hydraulics
- XTR di2 rear derailleur
- keep my Sram 10-42 cassette
- keep the same Sram rotors/ post mount disc brakes
- keep the same cranks and chainring

It this swap pretty straight forward? Or am I totally missing something here? Just want to be sure before I start ordering the shifters and rear derailleur.

Thank you!!

FYI You might get a bigger and more qualified audience on the Components/Wrenching branch.

I have no idea myself.

Am I reading that right? You want to use Ultegra shifters with Sram Brakes?

This. Sram and Shimano hydraulics cannot be mixed. At all. Everything else you mentioned should be just fine but you will need to change your brake calipers. I don't know if Shimano offers post mount road calipers anymore, if not I had heard of some people using XT level calipers with Shimano road levers at one point but I don't know how wide spread that compatibility ran.

Hope also makes the RX4 road caliper that is Shimano compatible and post mount. It's 4 piston too.
