Can anyone tell me if these mounts are the same or similar? I'm talking a dia-compe 990 or under-chainstay mounted brake, or the new road standard.
U brake:
Direct mount:
I'll clarify that I understand one is on a BMX and the other is on a road bike, as well as that one has studs while the other recessed holes. I'll also state that I believe I can run the direct mount brake on the older standard, but for my own curiousity I'm trying to figure out if anybody has any sort of documentation or history that suggests shimano simply repurposed the standard for their new brake setup. I can't find anything out there indicating for or against.
