JP, those are just modern Dia Compe 750s. I needed a drop link for the rear caliper. Had I not wanted this bike to look original aside from the wheels I would have went with Tektro dual pivots. David's right, they're just superior to single pivots or centerpulls. They even make some crazy dual pivots for balloon tire bikes with 90-110mm reach or somesuch crazy number.

I have man hands so I don't really have trouble braking with centerpulls and non-aero levers. That said, I prefer the mechanical advantage of aero levers and I don't usually waste time with brake pads that don't have a toe in adjustment feature. I love old school bikes, but adjustable pad holders are a marked improvement and aren't usually an eyesore.
