They're single pivot with a bell crank arrangement to increase leverage.

I didn't understand what you meant by "modulation". In automotive brakes
the term would indicate some kind of pulsation in the braking system.
The pads were too new and I was using them on a fairly new set of Mavic
Open Pro rims with rough machined sides so it was hard to tell how
controllable they would be.
I gave them a good workout today and yes they are very controllable but
they're the first road brakes that I've been able to lock up since I
started riding again last year. I have to remember the old trick of
sliding back on the seat in a hard stop - they will definitely throw you
forward.
This afternoon I had a minivan pull in front of me and stop. With any of
the brakes on my other road bikes I would have mated with the back door.
