I’m building up my new bike from used and new parts. Just got around to mounting brakes and getting a little confused as to what brackets I need. The brakes are Sram guide RS going on 2015 Rockshox Revs and a 2016 Giant Anthem advanced. 180mm discs front and rear. I’ve looked at the Sram chart on their site but none the wiser.

Anyone got any ideas please?

I’d imagine both fork and frame are post mount. So sram/avid front and rear 180mm post to post adapters.
Merlin seems to have appropriate ones.
