Hello,
I just bought a 2019 Giant Defy Advanced 2, with Giant's "Conduct SL Disc" brake system and it's the only thing about the bike I don't like, for many reasons. But my question is, are the rotor mount holes "universal" i.e. can I replace the Giant system with Shimano 105 mechanical brakes? Any help would be greatly appreciated.
 
If you are going to fit mechanical disc brakes then the rotors will be OK, you will need to choose flat mount calipers to fit the frame.

What don't you like about them if you don't mind me asking?
