After an hour of googling i could not find any solid info about direct mount brake standards. As I understand it so far shimano and TRP at one time used different bolt widths and sizes, but now may be cross compatible? I’m looking to change out the TRP brakes on my Argon 18 Nitrogen because they are a nightmare to work on or recable. I was hoping to find out what the standards are currently that was I can find a different set of brakes to install.
I believe all of the current direct mount frames use the same width for the brake bosses. Shimano, SRAM, TRP, ee, etc will work.
